Occlusion Theory

A vocabulary for conscious attention

Jhana, Focusing, IFS, vipassana, and flow all describe inner experience in different languages. This is an attempt at a shared vocabulary, like musical notation. The goal is a unified state space where the trajectory of any attention training practice can be located.

A work in progress. I enjoy finding structure in the wide variety of human experience. Feedback welcome.

What this does

To see a World in a Grain of Sand
And a Heaven in a Wild Flower
Hold Infinity in the palm of your hand
And Eternity in an hour

1. Core Concepts

Attending to one thing blinds us to another.
Practices differ in where they direct attention.
All can be described in terms of how they foreground various aspects of experience.

What we are blind to in any moment is as informative as what we notice.

Right now, you're looking through these words at meaning (transparent). If you notice the shapes of letters, they become appearance (opaque). The hum of your environment has likely dropped out entirely (blind).

These three modes—T, O, B—are the basic vocabulary. Everything else builds on them.

Three Modes

Mode Symbol Experience Example
Transparent T Seen through. Feels like reality. You see the room, not "visual processing"
Opaque O Seen as. Noticed as appearance. "That's just a thought"—seeing the thought as thought
Blind B Not in experience at all. The refrigerator hum you stopped hearing

Interactive Lens Model

Light (experience) passes through 8 lenses. Click any lens to cycle its state. T = clear (seen through), O = frosted (seen as), B = capped (blocked).

2. Framework

2.1 Regions of Experience

We divide experience into eight regions:

Symbol Region Content
w🌍 WorldExternal sensory content (sights, sounds, etc.)
b🫀 BodySomatic/interoceptive sensations
e💗 EmotionAffective states, feelings
t💭 ThoughtCognitive content, concepts, narrative
s👤 SelfSense of being a subject, the "I"
a🎯 AttentionThe process of attending itself
m🔮 ModelThe predictive construction process
✨ GroundEmptiness, space, absence, the background
Structure of the Regions

The eight regions are not a simple hierarchy. They form two distinct groups with different relational structures:

Content Network (w, b, e, t): Bidirectional indexing

These four regions mutually influence each other. Any can activate any other:

  • Upward: Body → Emotion → Thought (interoception shapes affect shapes cognition)
  • Downward: Thought → Emotion → Body (cognition indexes affect indexes soma)
  • Lateral: World ↔ all (perception triggers and is shaped by internal states)
Examples of bidirectional flow:
  • Seeing a snake (w) → fear (e) → racing heart (b) → "danger" (t)
  • Remembering loss (t) → grief (e) → chest tightness (b)
  • Stomach pain (b) → irritability (e) → negative thoughts (t) → world seems hostile (w)

Structural Hierarchy (s, a, m, ∅): Foundational ordering

These four regions are hierarchically organized, with each level more foundational:

  • Self (s): emerges from and organizes the content network
  • Attention (a): the selection mechanism that shapes what appears
  • Model (m): the predictive framework constructing all experience
  • Ground (∅): the space/emptiness in which anything can appear

🤝 Relation (r): The encompassing context

Relation is the field within which the entire system arises:

  • We co-determine each other's states (your attention shapes my attention)
  • Self emerges from relation (we become selves through others)
  • "My" ground is not separate from "our" ground
  • Every T/O/B configuration is relationally situated

Sources: Buber's I-Thou, Ubuntu, Buddhist interdependence, attachment theory

This explains why contemplative progress often moves "inward": making the structural regions visible (O) requires first stabilizing the content network.

🤝 ─── Relation (r) ─── the field everything arises within ─── 🤝
── Content (indexing chain) ──
🌍 World (w)       💭 Thought (t)
   ↓                      ↑
🫀 Body (b)  →  💗 Emotion (e)
── organized by ──
── Structural (bidirectional) ──
👤 Self (s)
🎯 Attention (a)
🔮 Model (m)
✨ Ground (∅): most foundational
🤝 ─── we co-determine each other ─── 🤝

World impacts body. Body states are indexed as emotions.
Emotions are indexed as thoughts. Thoughts can also re-trigger the chain.
Deeper structures (below) organize surface experience (above).
The entire system arises within a relational field: there is no isolated subject.

2.2 State Notation

A consciousness state is a function σ: Regions → {T, O, B}

We write states as 8-tuples:

σ = (w, b, e, t, s, a, m, ∅)
Example: Ordinary Waking Consciousness

σordinary = (T, T, T, T, T, B, B, B)

World, body, emotion, thought, self all transparent (taken as real).
Attention, model, ground all blind (not noticed).
Example: Deep Vipassana

σvipassana = (O, O, O, O, O, O, O, B)

Everything opaque: seen as arising, constructed, not-self.
Only ground remains blind.
Example: Nondual / Dzogchen

σnondual = (T, T, T, T, B, T, O, T)

Experience flows transparently, self is blind (no observer).
Ground/emptiness becomes transparent: the space in which all appears.

2.3 Transformations (Practices)

A practice is a function π: State → State

We write transformations as:

π: region₁→mode₁, region₂→mode₂, ...
Example: Noting Practice

πnoting: w→O, b→O, e→O, t→O, a→O
"Make everything opaque by labeling it as it arises"

Composition: Practices compose: (π₁ ∘ π₂)(σ) = π₁(π₂(σ))

Order matters. Shamatha then Vipassana ≠ Vipassana then Shamatha.

2.4 Derived Quantities

Quantity Definition Interpretation
Transparency Load |T| = count of T regions How much is "taken as real"
Opacity Load |O| = count of O regions How much is "seen as constructed"
Blindness Load |B| = count of B regions How much is excluded
Insight Index |O| / (|T| + |O|) Proportion seen as construction
Compression |B| / 8 How narrow the aperture
Groundedness 1 if ∅∈{T,O}, else 0 Whether emptiness is present

3. Cross-Framework Mapping

If the 8 regions are not arbitrary, they should map onto independent frameworks. Here's a sketch of correspondences:

OT Region Buddhist (Skandhas) Phenomenology IFS Predictive Processing
World (w) Rūpa (form), Saññā (perception) Noema (object) External triggers Sensory input
Body (b) Rūpa (form), Vedanā (feeling) Hyle (sensory data) Somatic markers Interoceptive signals
Emotion (e) Vedanā (feeling), Saṅkhāra (formations) Affective intentionality Parts' feelings Valence predictions
Thought (t) Saññā (perception), Saṅkhāra (formations) Noetic content Manager narratives Explicit predictions
Self (s) Saṅkhāra (formations), Viññāṇa (consciousness) Transcendental ego Blended parts Self-model
Attention (a) Viññāṇa (consciousness) Noesis (act) Witnessing Precision weighting
Model (m) Saṅkhāra (formations) Horizon, lifeworld System beliefs Generative model
Ground (∅) Viññāṇa (pure awareness) Pre-reflective consciousness Self (capital S) Prior to prediction

This is a sketch. Each row deserves deeper investigation. The convergences and divergences are themselves data.

4. Energetic Constraints

Without constraints, this is taxonomy. With constraints, it becomes physics. The following constraints generate predictions about what's possible, what's stable, and what requires effort.

4.1 Limited Attention

CONSTRAINT 1: Conservation
Total attention is fixed. Noticing (O) costs more than experiencing (T). Ignoring (B) is cheap.

You can't pay attention to everything at once. More self-awareness means either less absorption in the world or a narrower focus.

Prediction: More self-awareness means either less absorption in the world or a narrower focus. Meditators who watch their mind closely should show reduced sensory richness or narrowed attention.

4.2 Opacity Cost

CONSTRAINT 2: Energy Ordering
Noticing (O) is most effortful. Experiencing (T) is easier. Ignoring (B) is easiest.

Opacity requires maintaining content plus awareness that it's an appearance. Double the work.

Prediction: High-O states are unstable and tiring. System naturally drifts toward T (absorption) or B (exclusion). Sustained vipassana is more metabolically demanding than jhana.

4.3 Adjacency Constraint

CONSTRAINT 3: Adjacency
States transition through neighbors: T ↔ O ↔ B. You can't go directly from T to B.

To let go of something, you first have to notice it. You can't unsee what you never saw.

Prediction: "Suppression" (T→B directly) is unstable, content rebounds. "Letting go" (T→O→B) is stable. Trauma therapy must include T→O (feeling it) before B→(release): can't skip.

4.4 Blindness Momentum

CONSTRAINT 4: Hysteresis
The longer something is blind, the harder it is to retrieve.

Blindness accumulates inertia. Long-ignored content becomes hard to access.

Prediction: Repression duration predicts therapeutic difficulty. Jhana depth predicts exit jarring-ness. "Dark night" phenomena occur when long-B content is forced to O.

4.5 Forbidden Configurations

CONSTRAINT 5: Partition Rules
Some combinations are impossible:
• Can't have self transparent while watching attention
• Emptiness requires something to be empty of
• The model can never be fully transparent (it IS the transparency)
Prediction: Some practice goals are impossible to combine simultaneously. The "witness" (s=T, a=O) must eventually collapse.

4.6 Free Energy Gradient

CONSTRAINT 6: Attractor Dynamics
Opacity (O) is unstable. The system pulls toward either absorption (T) or exclusion (B).

O is inherently unstable. The system "wants" to resolve opacity: either by absorbing (→T) or excluding (→B).

Prediction: Without active effort, O decays. Insight fades. Practice maintains O against the gradient. "Integration" is controlled O→T transition.

4.7 Shevirat ha-Kelim (Shattering)

CONSTRAINT 7: Rate Limit
Too much becoming visible too fast overwhelms the system.

From Lurianic Kabbalah: too much light too fast shatters the vessels. The system has limited capacity to process sudden revelation.

Prediction: Rapid B→O (psychedelic breakthrough, forced memory recovery, premature insight) causes destabilization. "Spiritual emergency" = rate limit exceeded. Integration time is non-negotiable.

4.8 Computational Frame

The constraints above may have a deeper explanation: T, O, and B correspond to different computational regimes with different resource costs. Working memory, attentional capacity, and cognitive load offer a path toward grounding these ideas empirically.

Complexity Costs of States

State Computation Complexity Resource Cost
T Automatic processing, no meta-representation Low Baseline
O Meta-representation: representing the representation High Expensive
B Not computed, pruned from processing Zero Free (saves resources)

Why O is expensive: Opacity requires maintaining two simultaneous representations: the content itself AND a model of that content as constructed/appearance. This is metacognition, and metacognition has computational overhead.

The Indexing Chain as Compression

The content regions (w→b→e→t) form a compression hierarchy:

Region Dimensionality Information
🌍 World Very high Raw sensory stream (millions of bits/sec)
🫀 Body High Interoceptive state (thousands of signals)
💗 Emotion Medium Compressed body index (valence, arousal, ~dozens of categories)
💭 Thought Low Symbolic compression (discrete concepts, language)

Each level up the chain is a lossy compression of the level below. Emotions are summaries of body states. Thoughts are summaries of emotions.

Example: A complex bodily state (elevated heart rate, shallow breathing, muscle tension, cortisol spike) gets compressed into "anxiety" (emotion), which gets compressed into "I'm worried about the meeting" (thought).

Attention as Resource Allocation

Attention is the mechanism that allocates finite computational resources across regions. It determines:

  • What gets processed at all (T or O) vs. pruned (B)
  • What gets meta-represented (O) vs. just processed (T)
  • How much bandwidth each region receives
Attention entails estimating uncertainty during hierarchical inference about the causes of sensory input.
— Karl Friston, via the free-energy principle

In OT terms: attention determines what gets precision-weighted (T/O) vs. pruned as low-salience (B). High precision = opaque or transparent. Low precision = blind.

This explains why attention (a) sits in the structural hierarchy: it's the resource allocator that shapes the entire computation.

Why B is Sometimes Optimal

Blindness saves resources:

Computational Prediction: Optimal consciousness isn't maximum awareness (all O). It's optimal allocation: the right things T, the right things O, the right things B, dynamically adjusted.

Skill Acquisition as Complexity Reduction

Stage State Computation
Learning O High complexity: explicit rules, conscious monitoring
Practicing O→T Chunking: subskills become automatic
Mastery T Low complexity: compiled, effortless
Teaching T→O De-compilation: making implicit explicit again

Mastery paradox: True expertise requires the ability to shift flexibly between T (effortless performance) and O (reflective analysis). This is computationally expensive: maintaining both compiled and decompiled versions.

Information-Theoretic Formulation

The T/O/B distinction can be formalized in information-theoretic terms. Let W denote the global workspace (reportable contents, working memory) and R denote a region.

State I(R; Behavior) I(R; Report) Interpretation
T High Low Information drives action but can't be described
O High High Information drives action and can be described
B ~Zero Zero Information gated out before reaching workspace

Channel capacity constraint: Total information flow into the workspace is bounded:

Σᵢ I(Rᵢ; W) ≤ C

where C is total attentional capacity. Since O requires meta-representation (representing the representation), it costs more bits than T:

cost(O) > cost(T) > cost(B) = 0

Testable Predictions

Summary

COMPUTATIONAL FRAME
Consciousness = resource-bounded computation over phenomenal content.

T = compiled processing (fast, cheap, inflexible)
O = interpreted processing (slow, expensive, flexible)
B = pruned (no processing, maximum savings)

Development = learning optimal allocation.
Practice = training the allocator.
Pathology = stuck allocation.

4.9 Flow Model

Attention can be modeled as a conserved fluid flowing through the network of regions.

Basic Setup

T/O/B as Flow States

State Flow Property Dynamics
T High throughput Attention flows through without pooling. Content processed automatically.
O Pooled / dammed Attention accumulates. Inflow > outflow. Active holding requires effort.
B Disconnected No flow. Region cut off from the network. Valve closed.

Dynamics

dar/dt = Σj(Fjr - Frj) + Sr - Dr

Where:

What Practices Do

Practice Flow Operation
Concentration (jhana) Close valves to w, t, e. Pool attention in narrowing focus.
Vipassana Open all valves. Increase global circulation. Notice flow itself (a→O).
IFS Open valve to specific e/s region. Pool attention there. Then drain (integrate).
Flow state Close s valve. Open w/task valve. High throughput, no pooling.

Attractors

Stable flow configurations are attractors. Ordinary consciousness is a default attractor. Practices temporarily shift to other attractors. Trait change = reshaping the attractor landscape.

Testable: If flow model is correct, attention shifts should follow network structure (adjacent regions easier to shift between). Pooling (O) should show measurable dwell time increases. Disconnection (B) should show reduced functional connectivity in neuroimaging.

Concrete Examples

Breath Counting (Shamatha)

Instructions: Count breaths 1-10, return when distracted.

What happens:
  1. World becomes B: sounds fade out
  2. Thoughts become B: no longer engaging
  3. Body (breath) becomes O: watching it
  4. Attention becomes O: you notice when you're focused
  5. Deep: breath becomes T: you ARE breathing, not watching
Progression:
(TTTTTBBB) → (BOBBTOBB) → (BTBBBBBB)

Skill trained: Moving regions to B. Choosing what to exclude.
Noting (Vipassana)

Instructions: Label each experience: "thinking", "hearing", "wanting"...

What happens:
  1. Sound arises → note "hearing" → sound becomes O
  2. Thought arises → note "thinking" → thought becomes O
  3. Self notices → note "selfing" → self becomes O
  4. Deep: even the noting is noted → model glimpsed → O
Progression:
(TTTTTBBB) → (OOOOTOBB) → (OOOOOOOB)

Skill trained: Moving regions to O. Seeing construction.
Self-Inquiry ("Who am I?")

Instructions: Ask "Who am I?" and look for the asker.

What happens:
  1. Look for "I" in body → not there → body becomes O
  2. Look for "I" in thoughts → they pass → thought becomes O
  3. Look for the looker → can't find → self becomes... B?
  4. What remains: just seeing. Ground becomes T.
Progression:
(TTTTTBBB) → (OOOOOOBB) → (TTTTBTOT)

Skill trained: s→OB. Dissolving the self-construct.
Jhana (Absorption States) — Detailed Stages
Access Concentration

Guidance: "Rest attention on the breath. When the mind wanders, gently return."

What's happening: Training stable attention. World fades (B), thought quiets (B), body-breath becomes object (O).

(BOTBTOBB)
First Jhana

Guidance: "Notice the pleasantness arising from concentration. Let attention rest in that pleasure (pīti)."

What's happening: Emotion becomes primary object. Pleasant feeling (O then T) as you absorb into it. Applied and sustained thought still present but fading.

Jhana factors: applied thought, sustained thought, pīti (rapture), sukha (happiness), one-pointedness

(BTTOTOBB)
Second Jhana

Guidance: "Let go of directing attention. Rest in the joy itself. No more effortful returning."

What's happening: Applied thought drops (B). Attention becomes T—no longer watching yourself concentrate. Just joy.

Jhana factors: pīti, sukha, one-pointedness (no more applied/sustained thought)

(BTTBTTBB)
Third Jhana

Guidance: "Let the energetic rapture fade. Rest in the quieter contentment beneath it."

What's happening: Pīti (rapture) fades (B). Subtler sukha (contentment) remains. Body very quiet, equanimity emerging.

Jhana factors: sukha, one-pointedness, equanimity emerging

(BTTBTTBB) — emotion even more T
Fourth Jhana

Guidance: "Let even contentment go. Rest in pure equanimity, neither pleasant nor unpleasant."

What's happening: Emotion becomes B—not suppressed, just not arising. Pure equanimity. Breath may become very subtle or seem to stop.

Jhana factors: equanimity, one-pointedness (no sukha)

(BTBBTTBO) — ground starting to shimmer

Pattern: Jhana progression systematically moves regions from O→T→B, each stage releasing a grosser factor to reveal a subtler one. The "absorption" is increasing T with decreasing O.

Focusing (Gendlin) — Step by Step
Step 1: Clearing a Space

Guidance: "What's between you and feeling fine? Don't go inside them—just list them and set each aside."

What's happening: Making thoughts/concerns O—seeing them as objects, not being inside them. Creating distance.

t: TO
Step 2: Felt Sense

Guidance: "Choose one issue. Don't go inside it—feel the whole of it in your body. What's the felt sense of this whole thing?"

What's happening: Attention shifts to body (O). Looking for pre-verbal, holistic body-sense of the issue. Thought stays O (not engaging content).

b: BO, e: emerging
Step 3: Handle

Guidance: "What word, phrase, or image captures the quality of this felt sense? Tight? Heavy? Stuck?"

What's happening: Finding the right symbol makes emotion O—the vague felt sense gets a handle. Resonance check: does the word fit the feeling?

e: vague→O (crystallized)
Step 4: Resonating

Guidance: "Go back and forth between the felt sense and the handle. Does it fit? Adjust until it resonates."

What's happening: Body and symbol cross-checking. When they match: slight release, "felt shift." Body truth (T) validates symbolic knowing (O).

b↔e↔t oscillating between O and T
Step 5: Asking

Guidance: "Ask the felt sense: What is it about this whole thing that makes it so [handle]? What does it need?"

What's happening: Letting the body answer, not the mind. Staying with O on body-sense while thought stays B (not problem-solving).

b: O, t: B (receptive waiting)
Step 6: Receiving

Guidance: "Welcome whatever comes. Don't critique it. Let your body respond to what emerged."

What's happening: Insight arrives. Felt shift—something releases. New understanding becomes T (obvious), old stuck pattern now O (seen, no longer controlling).

Shift: stuck pattern TOB

Pattern: Focusing uses the body as truth-ground. By making bodily felt sense O, implicit emotional meaning surfaces. The "felt shift" is a pattern moving from T (controlling invisibly) to O (seen) to B (released).

IFS (Internal Family Systems) — Working with Parts
Finding a Part

Guidance: "Notice a feeling or reaction you'd like to explore. Where do you feel it in your body?"

What's happening: What was T (automatic reaction you were identified with) becomes O (a "part" you can observe).

e: TO, s: still T
Unblending

Guidance: "Ask the part to separate from you a little, so you can see it better. How do you feel toward this part?"

What's happening: Creating distance between Self and part. If you feel critical/afraid → that's another part (blended). Self should feel curious, compassionate.

s: TO (differentiating Self from part)
Getting to Know the Part

Guidance: "Ask the part: What do you want me to know? What are you afraid would happen if you didn't do this job?"

What's happening: The part's logic becomes O—you see why it does what it does. It has a positive intent, even if the behavior is problematic.

t (part's beliefs): TO
Finding the Exile

Guidance: "Ask the protective part: Who are you protecting? What younger part would be hurt if you stopped?"

What's happening: Discovering the exiled part (wounded, usually young) that the protector guards. Making the exile O requires the protector to step back.

Deeper layer: BO
Witnessing and Unburdening

Guidance: "Be with the exile. Let it show you what happened. Offer it what it needed then."

What's happening: Self witnesses the exile's pain (O). The exile feels seen. Burden (stuck belief/feeling) releases—moves from O to B.

Unburdening: trauma pattern TOB
Integration

Guidance: "Invite the part to take on a new role. What would it like to do now that it's not carrying this burden?"

What's happening: Part integrates—its energy becomes available without the old pattern. Self remains T (you don't see yourself, you just are). Part becomes T too (no longer a separate "thing").

Integration: part moves OT

Pattern: IFS systematically makes parts O (unblending), then finds what they protect (B→O), then releases burdens (O→B). "Self" is what remains when parts unblend—the aware, compassionate witness.

Metta (Loving-Kindness) — Phrase Progression
Self-Directed

Guidance: "May I be happy. May I be healthy. May I be safe. May I live with ease."

What's happening: Deliberately cultivating emotion (OT). The wish becomes the feeling. Self as object of care.

e: constructed (O) → felt (T)
Benefactor

Guidance: "Bring to mind someone who loves you easily. May they be happy..."

What's happening: Using relationship to access emotion. The feeling of being loved makes metta T (natural, not forced). World enters via memory (O).

w: O (imagined), e: T
Neutral Person

Guidance: "Someone you neither like nor dislike. The cashier, a neighbor. May they be happy..."

What's happening: Extending metta beyond bias. The "neutrality" becomes O—you see you've been indifferent. Metta extends: their wellbeing now matters.

Habitual indifference: TO
Difficult Person

Guidance: "Someone you have difficulty with. May they be happy..."

What's happening: Aversion arises—now O (seen, not acted from). Metta practice holds both: the wish and the resistance. Gradually resistance softens.

Aversion: TOB
All Beings

Guidance: "All beings everywhere. May all beings be happy..."

What's happening: Self/other boundary softens. The categories "self," "friend," "enemy" become O then B. Just metta, boundless.

s: TOB, e: T (boundless)

Pattern: Metta uses deliberate emotion-construction (O) that becomes natural (T), while systematically dissolving the self/other boundary that limits love.

6. The Potential Landscape

If the constraints define an energy function, practices trace paths through a potential landscape. Some configurations are valleys (stable attractors), some are peaks (unstable), some are forbidden (impossible).

Key Regions

Region Characteristics Practices
Ordinary Basin High |T|, low |O|, low |B|. Default attractor. None needed: you fall here naturally
Concentration Ridge High |B|, moderate |T|, low |O|. Narrow but stable. Shamatha, Jhana, TM
Insight Peak High |O|. Unstable, high energy, transformative. Vipassana, noting, inquiry
Nondual Valley High |T|, s=B, ∅=T. Stable once reached. Dzogchen, Advaita, Zen
Relational Plateau Moderate |O| on s, shared attention. Circling, NVC, Metta

Developmental Timeline (Kegan Stages)

7. Development as Occlusion

Occlusion Theory connects to developmental psychology, particularly Robert Kegan's Subject-Object theory.

Kegan's Core Insight: Development is the progressive movement of psychological content from subject (what you ARE, can't see) to object (what you HAVE, can examine).

In OD terms:

Kegan Stage What becomes O (object) What remains T (subject)
2 → 3 Impulses, desires Relationships, mutuality
3 → 4 Others' expectations, relationships Self-authorship, identity
4 → 5 Self-system, ideology Inter-being, paradox
5 → ? Subject-object structure itself ??? (nondual territory)

The OD Addition to Kegan

Kegan's framework has Subject and Object. OD adds Blind.

Development isn't just T→O. It also involves:

Development is the progressive capacity to choose your occlusions rather than be chosen by them.
Integration: Development, contemplative training, and therapy all involve the same dynamics: learning to manage the T/O/B partition skillfully.

Other Developmental Phenomena

OD's framework extends beyond Kegan to explain a range of developmental phenomena:

Piaget's Cognitive Development

StageWhat's Transparent (T)What Becomes Opaque (O)
SensorimotorImmediate sensation
PreoperationalOwn perspectiveObject permanence
ConcreteConcrete logicMultiple perspectives
FormalAbstract systemsConcrete operations

OD insight: Each stage makes previous cognitive operations visible (O) while operating through new invisible structures (T).

Attachment Patterns

Attachment styles can be understood as stable occlusion patterns formed early:

  • Secure: e=O, s=O: emotions and self visible, flexible
  • Avoidant: e=B, s=T: emotions suppressed, hyperindependent self
  • Anxious: e=T, s=B: flooded by emotions, self occluded
  • Disorganized: Unstable oscillation between patterns

Earned secure attachment = learning to shift e and s between T/O flexibly.

Trauma and PTSD

Trauma as Forced Occlusion: Overwhelming experience creates involuntary B states: content that cannot be seen but still operates.

Skill Acquisition (Dreyfus Model)

LevelSkill StatusOD Translation
NoviceFollowing rules consciouslySkill = O (effortful, visible)
CompetentContext-dependent judgmentRules → T, context → O
ProficientIntuitive recognitionMost skill → T (automatic)
ExpertEmbodied masterySkill = T (invisible, effortless)
MasterCan teach, make explicitCan shift T↔O at will

Mastery = the ability to make transparent skills opaque again (to teach or refine them).

Moral Development (Kohlberg)

LevelWhat's TransparentWhat's Opaque
Pre-conventionalSelf-interest, punishment
ConventionalSocial norms, rolesSelf-interest as one factor
Post-conventionalUniversal principlesSocial norms as constructed

Moral development = successive T→O transitions for the basis of ethical judgment.

Language Acquisition

Sapir-Whorf in OD terms: Language categories that remain T shape perception invisibly. Making them O (through learning other languages or linguistics) reveals their constructedness.

Identity Formation

Erikson's stages as occlusion patterns:

  • Identity diffusion: s=B (no stable self-representation)
  • Foreclosure: s=T (identity adopted uncritically, invisible)
  • Moratorium: s=O (actively examining identity options)
  • Achievement: s=flexible (can be T or O as needed)
Unifying Pattern: All developmental models describe the same fundamental process: making increasingly foundational structures visible (T→O) while operating through new invisible structures at a higher level.

8. Common Paths Across Traditions

Despite surface differences, contemplative traditions converge on similar sequences. OD reveals the underlying structure.

8.1 The Concentration Path

Pattern: Increase |B|, stabilize remaining T

Ordinary → Narrow focus → Deep absorption → Exit
TraditionNameOD Signature
BuddhistJhānaw→B, t→B, e→O→T
HinduSamādhi (savikalpa)w→B, t→B, s→T
ChristianRecollectionw→B, t→B, ∅→T
IslamicMuraqabaw→B, a→O, s→O
JewishHitbonenutw→B, t→O, ∅→T

Convergence: All narrow phenomenal bandwidth (increase |B|) to stabilize and deepen remaining experience.

8.2 The Insight Path

Pattern: Increase |O| systematically, see construction

Ordinary → Notice arising → See construction → Model glimpsed
TraditionNameOD Signature
BuddhistVipassanā*→O (everything noted)
HinduViveka (discrimination)s→O, t→O
StoicProsochet→O, e→O
PhenomenologyEpochéw→O, m→O

Convergence: All cultivate metacognition (T→O) to see through habitual identification.

8.3 The Surrender Path

Pattern: s→B, ∅→T (self dissolves, ground appears)

Ordinary → Self questioned → Self released → Groundless ground
TraditionNameOD Signature
BuddhistAnattās→O→B
HinduNeti netis→O→B, ∅→T
ChristianKenosiss→B, ∅→T
IslamicFanās→B, ∅→T
JewishBittuls→B

Convergence: All move the self-construct from transparent to blind, revealing what was always beneath.

8.4 The Dark Night

Pattern: Rapid B→O overwhelms capacity (Constraint 7 violated)

Practice → Familiar collapses → Everything opaque → Integration or crisis
TraditionNameWhat Happens
ChristianDark Night of the SoulGod-image (s,∅) collapses from T to O to seeming-B
BuddhistDukkha ñanasPleasant aspects blind, only suffering opaque
ZenGreat DoubtCertainty (t,s) forced to O, nothing holds
SufiHal of contractionPrevious expansion becomes inaccessible (T→B)
OD Explanation: The dark night occurs when the rate of B→O exceeds processing capacity. Content that was safely blind becomes suddenly opaque: and there's too much to integrate. The way through is slowing down (reduce d|O|/dt) or increasing capacity through support.

9. Interpersonal Occlusion Dynamics

OD extends beyond individual practice to relationships. What happens when two occlusion patterns meet?

9.1 Complementary Blindness

Claim: Relationships stabilize through complementary occlusion patterns. What you're blind to, I see. What I'm blind to, you see.

In healthy relationships, partners cover each other's blind spots:

Prediction: Relationship conflict often occurs when both partners are blind to the same thing (shared B) or both trying to make the same thing opaque (competing for O).

9.2 Love as Occlusion Pattern

What is love in OD terms?

Romantic Love (Early):
The beloved becomes hyper-transparent (T): you see the world through them. Your own self-boundaries become partially blind (s→B). Merge state.

Your s: TB, Their presence: BT
Mature Love:
The other becomes opaque (O): you see them as a separate being with their own interiority. You hold your own self (s=O) while holding theirs.

Your s: O, Their s: O (both seen as constructed, both honored)
Compassion (Mettā/Karuna):
The other's suffering becomes opaque to you (their e=O in your field). Your self becomes less opaque (s→T or s→B). You feel with them without losing yourself OR losing yourself deliberately.

Self-other boundary: flexible, permeable

9.3 Intersubjective Practices

PracticeWhat HappensOD Signature
Circling Make the relational field opaque: notice the "us" as it arises Shared s→O, attention on the between
NVC Make own feelings/needs opaque, make other's opaque too e→O, t→O (both parties)
Eye Gazing World blinds, other's face transparent, self oscillates T↔O↔B w→B, other→T, s→unstable
Co-Meditation Synchronize occlusion patterns: shared B, shared O State alignment between practitioners

9.4 Synchronization and Alternation

Healthy relationships alternate between:

Love is the willingness to be blind together, and the courage to make each other opaque.
Testable: Measure couples' attention patterns during conflict vs. harmony. Synchronization of eye tracking, physiological measures should correlate with relationship satisfaction and repair success.

10. Ethics of Occlusion

If consciousness is shaped by what it occludes, ethics becomes: What should be occluded?

10.1 Moral Blindness

Claim: Much of what we call "evil" involves strategic blindness: choosing not to see what would demand response.
PhenomenonOD StructureWhat's Blinded
Dehumanization Other's s=B, e=B Their interiority, suffering, selfhood
Bystander effect Other's e=B, own s=T Their need; self-protection transparent
Systemic oppression Collective B on certain groups Suffering rendered invisible by design
Willful ignorance Chosen B on inconvenient truth "I'd rather not know"
Moral progress = expanding what we make opaque (O) rather than blind (B). Seeing suffering AS suffering, rather than not seeing it at all.

10.2 Virtue as Occlusion Pattern

Classical virtues can be reframed as skilled occlusion:

VirtueOD PatternThe Skill
Courage e(fear)→O, not e→T See fear as fear, act anyway. Don't be possessed by it.
Temperance e(desire)→O or →B See impulse as impulse. Choose appropriate B on craving.
Justice Other's e,s→O Make the other's needs and selfhood opaque: visible, real.
Wisdom m→O (rare) See the construction process. Know when to T, O, or B.
Humility s→O See the self as constructed, not as ultimate truth.
Compassion Other's e→O, own s→B Their suffering visible, your self-protection dimmed.

10.3 The Ethics of Attention

Attention is not morally neutral. Where you look matters.

Example: Privilege as Afforded Blindness

Privilege often means you CAN blind yourself to things others cannot. The wealthy can blind themselves to poverty. The majority can blind themselves to discrimination. The healthy can blind themselves to illness.

Ethical use of privilege: Choose O where you could choose B. See what you're allowed to not see.

10.4 Responsibility for Blind Spots

ETHICAL PRINCIPLE
You are responsible for what you choose to blind yourself to.
"I didn't know" doesn't excuse chosen ignorance.

Three categories of B:

Moral maturity is taking responsibility for your occlusion choices: knowing that what you blind yourself to shapes who you become.

10.5 The Paradox of Necessary Blindness

Complete transparency (all O) is neither possible nor desirable:

Ethical mastery: The capacity to choose your occlusions consciously: knowing what you're not seeing, why, and at what cost.

11. Predictions

A theory is only as good as its falsifiable predictions. Occlusion Theory generates the following testable claims:

11.1 Neural Predictions

Prediction Measure
High |O| states show elevated prediction error signals P3b amplitude, anterior cingulate activity
High |B| states show reduced default mode activity fMRI DMN suppression
O-states have higher metabolic cost than T-states Glucose metabolism, oxygen consumption
s=B (self-blind) correlates with reduced self-referential processing mPFC deactivation
∅=T (ground transparent) correlates with altered sense of time/space Posterior cingulate, precuneus activity

11.2 Behavioral Predictions

Prediction Test
High |O| is unstable without effort Time-to-collapse from O-state without instruction
T→B direct (suppression) shows rebound; T→O→B doesn't Compare suppression vs. "noting then releasing" for intrusive thoughts
Rate of B→O is limited Titration speed in trauma therapy predicts outcomes
Practices with similar OD signatures feel similar Cluster practices by OD state; validate with phenomenological reports

11.3 Training Predictions

Prediction Test
|O| capacity increases with training Duration of sustained metacognition by practice hours
Expert meditators can reach forbidden-adjacent states Access to configurations impossible for beginners
Jhana depth (|B|) predicts difficulty of exit Transition time from deep jhana to ordinary
Sequence matters: shamatha→vipassana outperforms reverse Compare training order for insight outcomes

11.4 Clinical Predictions

Prediction Test
Depression = pathological T on negative content Depressed patients show reduced ability to O-ify rumination
Anxiety = pathological T on threat Anxious patients show threat content stuck in T
PTSD = forced O/T cycling on trauma, with B unavailable Trauma content resists stable B; intrusion = forced T
Dissociation = pathological B Dissociated content has high B→O retrieval cost
Spiritual emergency = rate limit exceeded Rapid practice intensification predicts destabilization

11.5 Experimental Protocols

Eye Tracking Validation

If T/O/B are real states with distinct computational signatures, they should produce measurable oculomotor differences:

State Fixations Pupil Scanpath
T(w) Medium, task-driven Baseline Goal-directed, low entropy
O(w) Longer, exploratory Dilated (metacognitive load) Open, higher entropy
B(w) Absent/random Constricted Disengaged
O(t) Defocused/still Dilated Minimal movement

Protocol: Participants receive guided instructions to enter each state while viewing scenes. Train classifier on eye data. Success = above-chance classification of T vs O vs B from gaze patterns alone.

VR/AR: Real-Time State Detection

Virtual reality with integrated eye tracking enables closed-loop experiments:

  1. Calibration: Guided state induction (T, O, B for multiple regions) while collecting eye/pupil data
  2. Classification: Train personalized model to infer current state in real-time (<100ms latency)
  3. Adaptation: Environment responds to inferred state:
    • O(w) detected → slow scene changes, enhance aesthetics
    • B(w) detected → simplify, reduce stimulation
    • High switching → stabilize scene
  4. Training: Provide feedback when target state achieved, gamify attentional flexibility
Prediction: Adaptive environments that respond to attentional state will improve subjective wellbeing, state stability, and task performance compared to static environments.

Clinical VR Applications

Unsupervised Region Discovery

The 8 regions (w, b, e, t, s, a, m, ∅) are proposed, not derived. Future work could discover region boundaries from data:

Approach: Collect high-dimensional state descriptions (self-report, physiology, behavior, neural) during diverse tasks and practices. Apply dimensionality reduction and clustering to find natural boundaries in the state space.

Method:

  1. Dense sampling: Experience sampling across many contexts—meditation, therapy, flow, daily life, altered states
  2. Multi-modal data: Combine self-report probes, eye tracking, HRV, EEG, behavioral measures
  3. Embedding: Learn low-dimensional representation of attentional states (VAE, contrastive learning)
  4. Clustering: Find natural groupings in the embedding space
  5. Validation: Do discovered clusters map onto proposed regions? Are there more? Fewer? Different boundaries?
Possible outcomes:
• Clusters align with proposed regions → framework validated
• Clusters suggest different boundaries → framework revised
• Clusters vary by individual/culture → regions are constructed, not universal
• No stable clusters → T/O/B may be real but regions are arbitrary

This would move Occlusion Theory from vocabulary toward empirically grounded model—or reveal where the vocabulary fails.

Falsification Criteria

The framework fails if:

12. Historical Lineage

Occlusion Theory synthesizes insights from multiple traditions:

"φύσις κρύπτεσθαι φιλεῖ": Nature loves to hide.
— Heraclitus
"ἁρμονίη ἀφανὴς φανερῆς κρείττων": The hidden harmony is better than the obvious.
— Heraclitus
Greek Sources
  • Heraclitus: Reality actively occludes itself. The logos is present but unseen.
  • Plato: Cave allegory: shadows (T), turning around (T→O), sun (∅→T).
  • Aristotle: Steresis (στέρησις): privation as cause. Absence shapes presence.
Western Philosophy
  • Spinoza: "An emotion ceases to be a passion as soon as we form a clear and distinct idea of it." Inadequate ideas (T) enslave; adequate ideas (O) liberate. Three kinds of knowledge: imagination (T), reason (O), intuition (∅→T).
  • Kant: Phenomena vs. noumena: we only access appearance, never thing-in-itself. The model (m) can never be T.
  • Husserl: Phenomenological reduction (epoché): suspending natural attitude (T→O) to see experience as experience.
  • Heidegger: Dasein absorbed in world (T); anxiety breaks absorption (T→O); being-toward-death reveals Ground.
Jewish Sources
  • Tzimtzum: Divine contraction creates space for creation. Strategic B enables structure.
  • Hester Panim: God's hiding is active, relational: concealment as intimacy.
  • Klipot/Birur: Pathological vs. holy occlusion. Some B traps, some liberates.
  • Bittul: Self-nullification (s→B) as practice.
Islamic Sources
  • Fana: Annihilation of self (s→B): the ego dissolves in divine presence.
  • Batin/Zahir: The hidden (B) and manifest (T): reality has inner and outer faces.
  • Hijab: Veils between human and divine: 70,000 veils of light and darkness to traverse.
  • Muraqaba: Watchfulness practice: making attention opaque (a→O) through self-observation.
Christian Mysticism
  • Apophatic theology: God known through negation: what God is NOT. Divine as ultimate B.
  • Cloud of Unknowing: "Put a cloud of forgetting beneath you": systematic B of all content to reach God.
  • Dark Night of the Soul: When familiar T collapses and O becomes overwhelming. The rate limit exceeded (Constraint 7). St. John of the Cross mapped this as necessary passage.
  • Centering Prayer: Release thoughts as they arise (t→B), rest in presence (∅→T).
Buddhist Sources
  • Avijja: Ignorance as root: not seeing (B) what's there.
  • Vipassana: Systematic T→O on all phenomena.
  • Jhana: Systematic increase of |B| for stability.
  • Sunyata: Emptiness: ∅→T as goal.
  • Dukkha ñanas: The "knowledges of suffering": when insight (O) becomes overwhelming. Buddhist dark night.
Western Psychology
  • Freud: Repression (pathological B), making unconscious conscious (B→O).
  • Kegan: Subject-object development (T→O for successive structures).
  • Gendlin: Felt sense: body's implicit knowing held in B, brought to O.
  • Metzinger: Phenomenal transparency: T as default, O as achievement.
Cognitive Science
  • Predictive Processing: T = prediction confirmed, O = prediction error, B = not predicted.
  • Attention Schema Theory: "Awareness is the brain's internal model of the process of attention." In OD: when a=O, you're running the attention schema. When a=B, attention operates without self-model. AST explains *that* we model attention; OD explains the *modes* of that modeling.
  • Compression Progress (Schmidhuber): "The agent finds observations interesting if they are not yet fully predictable but learnable." In OD: we're drawn to what's becoming opaque—patterns emerging from transparency, not yet blind from familiarity.
  • Global Workspace: What's "in" the workspace (T/O) vs. not (B).
What OT Adds: A unified formal framework with energetic constraints that generates predictions.

13. Clinical Applications

OT frames psychological conditions not as deficits but as different default allocation patterns: each with trade-offs. Pathology arises when patterns become stuck rather than flexibly deployed.

13.1 Mood Disorders

ConditionOT PatternKey Features
Depression e=T (stuck), t=T (stuck), s=T (fused) Negative affect/thoughts experienced as reality, not passing states. Difficulty achieving O ("I am depressed" vs "I notice depression"). World dimmed, low salience.
Anxiety m=T (threat predictions), b=T (arousal), a=stuck Threat predictions feel like facts. Can't background somatic arousal. Attention locked on threat, can't make B.
Bipolar (mania) w=intense T, e=T (elevated), s=inflated T World hypersalient. Energy/mood stuck T. Grandiose self experienced as reality. Reduced need for B (sleep).

13.2 Neurodivergence

ConditionOT PatternTrade-offs
ADHD a=unstable, w=hyperactive T, difficulty with intentional B Poor filtering but high novelty detection. Everything salient, hard to background. Rapid t→t switching (associative leaps).
Autism w=high O or intense T, m=more O than typical Sensory detail prominent, not backgrounded. Explicit rule-following (social = O) rather than transparent intuition. Less lossy compression: more detail retained.
Dyslexia Symbol processing remains O (effortful) Reading doesn't automate to T. Trade-off: often strong spatial/holistic processing.
Neurodivergence in OT: Not disorder but different allocation defaults. Autistic perception may retain detail neurotypicals compress away. ADHD attention may catch what focused attention misses. The cost is fitting neurotypical-designed environments.

13.3 Trauma-Related

ConditionOT PatternMechanism
PTSD Memory in B (dissociated) → sudden B→T (flashback) Traumatic content can't be made O (processed). Hypervigilance = can't B world/body. Dissociation = defensive T→B.
Complex PTSD s=unstable, e=dysregulated, r=disrupted Self never stabilized due to relational trauma. Emotion regulation impaired. Relational field itself feels unsafe.
Dissociative disorders b=B (depersonalization), w=B (derealization), s=fragmented Defensive B as protection. Multiple T configurations (parts). Structural regions destabilized.

13.4 Personality Patterns

ConditionOT PatternDynamics
Borderline s=oscillating T↔O↔B, e=rapid intense T Self unstable. Emotions flood as T. Splitting = other oscillates T (idealized) ↔ B (devalued). Difficulty holding stable O on self or other.
Narcissistic s=rigid T (grandiose), other=B Can't tolerate s→O (self-examination feels annihilating). Other not fully real (in B). Shame triggers defensive s→T inflation.
Avoidant s=painful O, r=avoided (B) Self experienced as defective (stuck O). Relational field made B to avoid anticipated rejection.
Schizoid r=B, e=B, rich inner t/m Relational and emotional regions backgrounded. Investment in thought/model (fantasy, abstraction).

13.5 Other Conditions

ConditionOT PatternMechanism
OCD t=intrusive (can't B), m=stuck O Unwanted thoughts won't background. Prediction errors stuck in O (something feels wrong, won't resolve). Compulsions = attempts to force O→T or O→B.
Addiction Craving=stuck T in b/e, a=hijacked Substance/behavior can't be made B. Attention captured. Loss of flexible allocation.
Psychosis m=T (constructions=reality), t=T (alien) Model predictions experienced as external reality. Hallucinations = internal content in w=T. Delusions = model stuck T, resistant to O. Self boundaries dissolve.
Eating disorders b=distorted T, s=fused with body image Body experienced through distorted T (can't achieve accurate O). Self collapsed into body evaluation.

13.6 Therapeutic Implications

Therapy as Occlusion Training:
  • CBT: t→O (see thoughts as thoughts, not facts)
  • Mindfulness: All regions → O (metacognitive awareness)
  • Somatic: b→O (make body sensations visible, processable)
  • Psychodynamic: B→O (make unconscious conscious)
  • EMDR: Controlled B→O for traumatic memory
  • DBT: e→O + distress tolerance (holding intense e in O)
  • IFS: s→O (parts work, seeing self-states as parts)
Clinical Prediction: Effective therapy increases flexible allocation: the ability to shift T↔O↔B as appropriate rather than being stuck in one configuration. Recovery is not a specific state but restored flexibility.
The Paradox of Healing: Many conditions involve being stuck in T (can't see the pattern). But the solution isn't permanent O (exhausting hyperawareness). It's regaining the ability to choose: to make something O when needed, then let it return to healthy T or B.

14. Limitations and Open Questions

Occlusion Theory is a framework, not a finished theory. Here are its known limitations and areas requiring further development.

14.1 Theoretical Limitations

LimitationThe ProblemPossible Response
Discrete vs. Continuous T/O/B are presented as discrete states, but phenomenology is likely continuous Could extend to continuous values: T(0.8), O(0.2): partial transparency
Region Boundaries The 8 regions are somewhat arbitrary. Why these? Are they fundamental? Empirical question: regions should be validated against phenomenological reports
Individual Differences People may have different baseline occlusion patterns or capacities Need to account for trait vs. state differences
Constraint Parameters The energetic constraints are postulated, not derived. What are the actual values of α, β, k? Requires empirical measurement: may vary by individual and context
Cultural Framing The framework draws heavily on Buddhist/Western categories. Other traditions may parse experience differently. Cross-cultural validation needed

14.2 Empirical Challenges

14.3 What OT Doesn't Explain

Outside the scope:
  • Content: OD addresses modes of relation (T/O/B), not what the content IS
  • Valence: Whether experience is pleasant/unpleasant is orthogonal to T/O/B
  • The hard problem: Why there is experience at all: OD presupposes consciousness
  • Agency: Who or what is doing the occluding? (Self-reference problem)
  • Unconscious processing: B is phenomenal absence, not cognitive absence

14.4 Open Questions

14.5 What Would Falsify OT?

FALSIFICATION CRITERIA
  • Finding stable high-O states that don't require effort (violates Constraint 2)
  • Demonstrating direct T→B transitions that don't rebound (violates Constraint 3)
  • Practices with identical OD signatures that feel phenomenologically distinct
  • Neural measures that don't distinguish T/O/B states
  • Cross-cultural data showing the T/O/B trichotomy is Western-specific
A theory that can't be wrong can't be right. OD makes specific claims that could be falsified.
