A source-first reading note for Hexagram 49, Ge (Revolution), with a reference translation, trigram frame, and one reversible observation practice.
Reference translation
Revolution. On the appointed day, the change wins men's trust. Sublime success. Furtherance through perseverance. Remorse vanishes. The Commentary: Revolution. Water and fire annihilate each other. Two daughters dwell together, but their wills do not accord — this is called Revolution. "On the appointed day trust is given": when change comes, the people believe in it. Inner clarity joined with joyousness; great success through correctness. When revolution is fitting, remorse departs. Heaven and earth bring revolution, and the four seasons are completed. Tang and Wu wrought their revolutions in accord with Heaven and in answer to men. Great indeed is the time of Revolution.

Context from the authority layer
In the Ge hexagram, amid the upheaval caused by the conflicting forces of "water and fire shooting at each other," only the nine-in-the-fourth line is out of position. The justification for revolution lies in a single misplaced line standing among five properly placed ones; the balance of revolutionary circumstance and power is five to one, and the catalyst for revolution is that mutually dependent things have come into the opposing condition of "water and fire extinguishing each other." This is the antagonistic mood of the Ge hexagram in the lower canon of the Zhou Yi.
Read the structure before the slogan
The lower trigram is 离 (火), associated in the bundled corpus with 丽; the upper trigram is 兑 (泽), associated with 悦. Read the lower trigram as the inner or starting field and the upper trigram as the outward field before turning the pattern into advice.
One accountable observation practice
Copy one concrete verb, condition, or image from the reference translation for Hexagram 49. Name one place where it is observable in the situation you are examining. Then choose one small step you can reverse and write the condition that would make you review it.
Common misread to avoid
Do not turn Revolution into a personality label, a guaranteed event, or a verdict about another person. The translation and trigram frame are source layers to examine, not an instruction to surrender judgment.
Source boundary
The reference translation and context are drawn from Yarrow's bundled structured Zhouyi authority layer. Yarrow keeps that layer separate from optional modern reflection. This page does not claim that Hexagram 49 was cast for your question.
