Abstract
This practice protocol describes a sequential interoceptive attention training (SIAT) method derived from traditional chakra‑based contemplative systems, reinterpreted through the lens of polyvagal theory (Porges, 2011) and interoceptive neuroscience (Craig, 2009). The protocol combines sensory isolation (eye mask, earplugs), deep pressure stimulation (weighted blanket), and structured attentional sequencing through seven body regions. The goal is not to validate any particular metaphysical claim, but to provide a phenomenological scaffold for individuals seeking to improve autonomic regulation, interoceptive accuracy, and state coherence. The protocol is offered as a practice guide for witnesses, not as a validated clinical intervention. All claims are phenomenological; users are encouraged to notice their own experience rather than adopt any particular belief system.

1. Introduction
Chronic exposure to extraction environments produces predictable patterns of autonomic dysregulation: hypervigilance (sympathetic dominance), emotional numbness (vagal withdrawal), attentional fragmentation, and reduced interoceptive accuracy (Humble, 2026a; Thayer & Lane, 2000). Traditional contemplative systems have long used structured attentional practices to address similar patterns. This protocol adapts one such system — the chakra‑based attention sequence — into a neutral, phenomenological practice framework.
Important caveat: This protocol does not assert the literal existence of chakras as energy centers. It uses the chakra sequence as a culturally available attentional scaffold — a way to guide attention through the body in a structured, repeatable order. Users are free to adopt or ignore the traditional interpretations.
2. Theoretical Grounding
2.1 Interoceptive Attention
Interoception — the perception of internal bodily states — is fundamental to emotional regulation and self‑awareness (Craig, 2009; Greenwood & Garfinkel, 2025). Structured interoceptive attention training has been shown to improve interoceptive accuracy, reduce rumination, and increase vagal tone (Farb et al., 2015; Bornemann & Singer, 2017).
2.2 Sensory Isolation and Deep Pressure
Reducing sensory load (eye mask, earplugs) lowers sympathetic threat detection (Porges, 2011). Deep pressure stimulation (weighted blanket) increases vagal activation and reduces cortisol (Chen et al., 2021; Mullen et al., 2008).
2.3 Sequential Attention
Sequential attentional scanning — moving attention systematically through body regions — has been shown to reduce default mode network activity and increase interoceptive salience (Farb et al., 2007; Fox et al., 2016).
3. Protocol Overview
3.1 Required Materials
| Item | Purpose |
|---|---|
| Eye mask | Blocks visual input; reduces threat scanning |
| Earplugs (or noise‑cancelling headphones) | Cuts auditory noise; lowers sympathetic activation |
| Weighted blanket (5‑10% of body weight) | Deep pressure; increases vagal tone |
| Comfortable surface (bed, couch, yoga mat) | Reduces postural effort |
| 15‑25 minutes of uninterrupted time | Allows the nervous system to settle |
3.2 Protocol Steps
Phase 1: Grounding (2‑3 minutes)
Lie supine. Apply eye mask and earplugs. Place weighted blanket over torso. Allow the body to sink into the surface. Notice the weight of the blanket holding you. Breathe naturally.
Phase 2: Sequential Interoceptive Attention
Move attention through the following body regions in order. At each region, spend 2‑3 minutes. Do not try to change anything. Simply notice what you feel — or do not feel. There is no “correct” sensation.
| Step | Region | Traditional Association | Attentional Focus |
|---|---|---|---|
| 1 | Base of spine / pelvis | Root | “I notice whatever sensations are present here — or absent.” |
| 2 | Lower abdomen | Sacral | “I notice warmth, coolness, movement, or stillness.” |
| 3 | Upper abdomen | Solar plexus | “I notice expansion, contraction, or neutral sensation.” |
| 4 | Chest / heart area | Heart | “I notice any sense of openness, tightness, or nothing in particular.” |
| 5 | Throat / neck | Throat | “I notice relaxation or tension in the jaw, throat, vocal cords.” |
| 6 | Brow / forehead | Third eye | “I notice pressure, tingling, or any sensation behind the eyes or brow.” |
| 7 | Top of head | Crown | “I notice lightness, pressure, expansion, or nothing at all.” |
Phase 3: Integration (3‑5 minutes)
After completing the sequence, rest without directing attention anywhere in particular. Notice the overall state of the body — calm, activated, neutral, or shifting. Do not judge. Simply observe.
Phase 4: Re‑orientation (1‑2 minutes)
Remove eye mask and earplugs slowly. Sit up gradually. Notice the return of external sensory input without rushing.
4. What You May Notice (Phenomenological Observations)
Users of this protocol have reported the following sensations. None are required. None are signs of “success” or “failure.”
| Sensation | Common Interpretation | Neutral Description |
|---|---|---|
| Tingling in hands or feet | “Qi flowing” | Paresthesia; possible increased blood flow or vagal activation |
| Warmth spreading | “Energy moving” | Vasodilation; parasympathetic engagement |
| Expansion beyond skin | “Field thickening” | Reduced body boundary vigilance; interoceptive expansion |
| Emotional release (tears, tremors) | “Trauma discharge” | Autonomic unloading; not pathological |
| Lightness at crown | “Crown activation” | Possible default mode network downregulation |
These sensations are reported but not guaranteed. Their absence does not indicate a problem.
5. Suggested Frequency and Duration
| Phase | Frequency | Duration per Session |
|---|---|---|
| Novice (weeks 1‑4) | 3‑4x per week | 15‑20 minutes |
| Intermediate (weeks 5‑12) | 4‑6x per week | 20‑25 minutes |
| Maintenance (ongoing) | 2‑3x per week | 15‑20 minutes |
Users are advised to start with shorter, less frequent sessions and increase gradually. Overactivation is possible.
6. Contraindications and Cautions
| Condition | Precaution |
|---|---|
| Active psychosis | Avoid; grounding practices only |
| Severe, unprocessed trauma | Go slowly; consider professional support |
| Dissociative disorders | Avoid extended sensory isolation |
| Pregnancy | Light weighted blanket only; avoid lying supine after first trimester |
| Epilepsy (photosensitive) | No visualizations required; focus on sensation only |
The protocol is not a substitute for medical or psychiatric care. Discontinue if it causes distress.
7. Integration with Coherence Metrics
For users who track their coherence using the CP‑25 or CP‑100 (Humble, 2026b; 2026c), this protocol may be used as a regulation practice. Suggested pre‑post tracking:
| Time | Action |
|---|---|
| Before | Complete CP‑25 (2‑3 minutes) |
| After | Complete CP‑25 again (2‑3 minutes) |
Users may notice changes in domain scores (physiological, cognitive, relational) over time. This is not a validation study; it is a self‑tracking suggestion.
8. Limitations
| Limitation | Mitigation |
|---|---|
| Not empirically validated | This is a practice protocol, not a clinical intervention |
| Culturally derived | The chakra sequence is used as a scaffold, not an ontological claim |
| Individual variation | Some users may find the sequence dysregulating; discontinue if so |
| No causal claims | Observed benefits may be due to rest, sensory isolation, or expectancy |
9. Conclusion
This protocol offers a structured, phenomenological approach to interoceptive attention training and autonomic regulation. It is not a research paper. It is a practice guide — for witnesses who wish to explore somatic regulation without committing to any particular metaphysical framework.
Users are encouraged to notice their own experience, track their own coherence, and adapt the protocol to their own nervous system.
“The sequence is a scaffold, not a doctrine. Use it if it helps. Set it aside if it does not.”
