The Science

Week 1 · The Observer

Polyvagal Theory

Your nervous system has a logic.

Polyvagal theory, developed by Stephen Porges, describes three states your autonomic nervous system cycles through: ventral vagal (safe and social), sympathetic (fight or flight), and dorsal vagal (shutdown).

You aren't choosing these states consciously. Your body detects safety or threat through a process called neuroception — a below-awareness scan that happens faster than thought.

Key Concept
Your reactions often aren't about what's happening now. They're your nervous system responding to a pattern it learned long ago. Understanding the pattern is the first step to changing it.

Why this matters for shadow work

Shadow material often lives in the body before it surfaces as thought. When you notice where you tighten, brace, or go numb, you're reading your nervous system's autobiography.

This week's exercises will help you map your own nervous system patterns — not to judge them, but to understand the intelligence behind them.

Vipassanā · Insight Meditation

“The whole technique is to observe yourself. Observe and do not react. Observe and remain equanimous. You are changing the habit pattern of the mind.”

S.N. Goenka

Vipassanā is one of India's oldest meditation techniques — a practice of seeing things as they really are. Its core instruction is radical: simply observe sensation without reacting. In shadow work, this becomes the foundation skill: learning to witness what arises in you without immediately fixing, fleeing, or fighting it.

Week 7 · Rewriting Patterns

Thought Record

Catching the Pattern

Think of a moment this week when you had a strong emotional reaction. Walk through it column by column. The goal isn't to change the thought — just to slow it down enough to see its parts.

Situation
Automatic Thought
What happened? Where were you?
What went through your mind?
Emotion (0-10)
Evidence For / Against
Name it. Rate its intensity.
What supports this thought? What challenges it?

Dialogue

Meeting the Manager

In IFS, a “manager” is a protective part that tries to keep you safe by controlling situations. Write a conversation between your curious Self and this protective part. Let it speak in its own voice. You're not arguing — you're listening.

What Your Body Remembers

Your body stores experiences the mind forgets. Trace your life along the river below. At each marker, write or draw a moment your body remembers — a sensation, a flinch, a warmth. Don't analyze. Just map.
