Instrument card — Yin & Yang

Core instrument I — yin and yang, the primary grammar

The ground

The Dao gives birth to one. One gives birth to two. Two give birth to three.
Laozi, Tao Te Ching, chapter 42

Yang full, light, moving, expansive, warm

Yin broken, dark, resting, receptive, cool

They aren't opposites, they're complements, and each carries the seed of the other. The question is never which is better. It's which season this is.

Four principles

Mutual dependenceYin and yang exist only in relation. Mastery lives in the movement between them.
Mutual transformationAt the maximum it turns. The shortest day is the beginning of more light.
Mutual consumptionMore yang means less yin. Stillness and rest replenish yin so yang can flow.
Continuous movementThe taijitu never stops turning. Presence is the ability to move with it.

Four stages, four seasons

Greater yangSummer. Full force, action, light. Yang within yang.
Lesser yangSpring. Emergence, movement starting. Yin within yang.
Lesser yinAutumn. Withdrawal, harvest. Yang within yin.
Greater yinWinter. Rest, hidden strength. Yin within yin.

Use this inside a single conversation, a training, a season or a career. The scale changes, the shape doesn't.

Which one do I refuse to practise, and why?

Core instrument II — open and closed energy

A line in the wrong place carries tension. That tension is information.

Open energy

Yang in a yin place

Productive tension. Potential is standing ready. Shir in its purest form, the moment before the movement.

For the coach. Invite, don't push. Watch the timing.

Closed energy

Yin in a yang place

Withdrawing tension. Energy consolidates. The spring that's still winter. Resistance is asking to be acknowledged.

For the coach. Acknowledge, give room. Don't force it.

Neutral state

Line in its own place

Alignment. No tension, no friction. Acting costs nothing because it flows. This is Hexagram 61.

For the coach. Keep the silence. Act from resonance.

The Five Phases — Wu Xing

Wood

木 Mù · spring · upward

Initiative, growth, vision, breaking through.

Too much: impatient, pushing.

Fire

火 Huǒ · summer · outward

Connection, passion, inspiring, being present.

Too much: scattered energy, burnout.

Earth

土 Tǔ · centre · stable

Nourishing, stabilising, trust, anchoring.

Too much: boundless, smothering.

Metal

金 Jīn · autumn · inward

Precision, discernment, letting go, evaluating.

Too much: rigid, hypercritical.

Water

水 Shuǐ · winter · deep

Strategy, reflection, patience, hidden strength.

Too much: indecisive, withdrawn.

The two cycles

Generating — 生 Shēng

Wood→Fire→Earth→Metal→Water→Wood

Know which phase the athlete is in and you know what they need in order to move.

Controlling — 克 Kè

Wood→Earth→Water→Fire→Metal→Wood

Keeps any one phase from taking over. The coach's self-regulating system.

Neidan — inner alchemy 内丹

Jing transforms into Qi. Qi transforms into Shen. Shen returns to the Dao.

精
JingEssence. Water.
氣
QiLife energy. Wood. Reached through water.
神
ShenSpirit. Heaven. Reached through fire.
☯
DaoStillness. Emptiness.

Jing exhausted and no technique works. Qi stagnant and Shen clouds over. The Five Phases show the way back.

Coaching scan

Five phases, in yourself and in the athlete

Phase	Coach, too much	Athlete, too much	What helps
Wood	Rushed, pushing, always taking initiative	Stubborn, overestimates themselves	Slow down. Earth or metal.
Fire	Overpassionate, attention everywhere	Everything at once, chasing connection	Depth. Water.
Earth	Smothering, no boundaries	Dependent, no initiative	Direction. Wood or metal.
Metal	Hypercritical, rigid	Perfectionism, fear of failing	Warmth and contact. Fire.
Water	Withdrawn, indecisive	Loss of motivation, isolation	Gentle movement. Invite wood.

No phase is wrong. Each one has its season. What matters is the movement, not the fixed point.
