Hexagram 49 of 64 · King Wen sequence
革 · gé
The lake above fire: skin shed, the day confirmed — transformation with a calendar, trusted only after it is believed.
Fire under the lake, skin shed on the appointed day: Revolution is the hexagram of genuine transformation — the change that is not undertaken until its time is confirmed, and not trusted until the people themselves believe it.
The counsel is about sequence: begin only when the day is right (a wrong-day revolution makes everyone a hostage), act with firm clarity, and expect the trust to lag the facts. Belief arrives late, the text says. It arrives. Do not confuse the lag with the failure.
