Revolution is the I Ching on fundamental change — and its central claim is that such change has a correct moment. The Chinese name carries the sense of molting: something sheds a skin because it has outgrown it.
The structure: Lake over Fire
Fire below, the lake above. Fire and water contend — the image of two things that cannot both stay as they are.
The Judgment
Revolution. On your own day you are believed. Supreme success. Furthering through perseverance. Remorse disappears.
The opener is the condition. Change of this kind succeeds on its own day — meaning when it is genuinely due, not merely desired. The text is unusually clear that timing, not resolve, is the deciding factor.
The Image
Fire in the lake: the image of Revolution. Thus the superior man sets the calendar in order and makes the seasons clear.
The instruction is about marking transitions properly. Change needs to be legible to the people living through it.
The lines
- Line 1 — Wrapped in the hide of a yellow cow.
- Line 2 — When one's own day comes, one may create revolution. Undertaking brings good fortune. No blame.
- Line 3 — Undertaking brings misfortune. Perseverance brings danger. When talk of revolution has gone the rounds three times, one may commit oneself, and men will believe him.
- Line 4 — Remorse disappears. Men believe him. Changing the form of government brings good fortune.
- Line 5 — The great man changes like a tiger. Even before he questions the oracle he is believed.
- Line 6 — The superior man changes like a panther. The inferior man molts in the face. Undertaking brings misfortune.
The animal imagery is about visibility. The tiger's change is unmistakable before it is explained; the panther's is subtler. Both are presented as complete in a way the inferior man's forced change is not.
A caution
This hexagram is sometimes quoted as endorsement for disruption. The text is more careful: line 3 is explicit that going too early is misfortune, and that the change must first have been discussed enough to be credible.
The tiger and the panther
Lines 5 and 6 use the two great cats to distinguish kinds of radical change. The tiger's markings are bold and legible from a distance; the panther's are subtler. Both are presented as whole, which is the point.
What fails is the inferior man's molt in line 6 — a change worn on the face rather than undergone.
