Overview
Decay — 山风蛊 (Gu) — decline.
The Hexagram
- Upper Trigram: Gen Mountain
- Lower Trigram: Xun Wind
- Chinese Name: 山风蛊 (Gu)
- English Name: Decay
- Key Meanings: Decline. Wind blocked by mountain — inherited problems needing correction.
The Judgment (Guà Cí)
Work on What Has Been Spoiled has supreme success. It furthers one to cross the great water.
The Image (Xiàng Cí)
The wind blows low on the mountain: the image of Decay. Thus the superior man stirs up the people and strengthens their spirit.
Symbolism Deep Dive
Mountain over Wind. Mountain (Gen, stillness, obstruction) above; Wind (Xun, penetration, influence) below. The wind is trapped beneath the mountain — it cannot circulate. What was once fresh becomes stale. This is decay — not sudden destruction but gradual stagnation. The hexagram is notable for its optimism: ‘work on what has been spoiled has supreme success.’ Decay is a call to action, not a verdict. The superior man ‘stirs up the people and strengthens their spirit’ — renewal begins with morale.
Modern Application
Every organization, relationship, and career eventually encounters Gu. The inherited codebase nobody wants to touch. The family pattern that repeats across generations. The company culture that calcified under previous leadership. The hexagram’s wisdom: addressing decay requires three days of preparation and three days of follow-through (lines in the text). Quick fixes fail. Deep cleaning works. Three days before: understand the root cause. Three days after: ensure the fix holds.
