Ge · Revolution
Change what must change, but earn trust before you move.
Judgment and Plain-Language Notes
Ge: On the si day, trust arrives. Supreme success. Steadfast correctness is beneficial. Regret vanishes.
The Tuan commentary describes water and fire putting each other out, two daughters under one roof whose wills do not meet: a tension that cannot hold, which is what change means. Trust arrives only on the appointed day, because a change has to be believed before it stands. The Xiang image is fire inside the lake, and the noble person orders the calendar and makes the seasons clear.
Dui above, Li below. Fire sits inside the lake and the two cannot share the space, so something has to give. Change here means replacing the old rather than patching it: the existing way no longer carries the weight. The key phrase in the judgement is that trust comes on the appointed day. Announcing a change does not make people follow it. The timing has to ripen and the trust has to be built first. The lines run from binding yourself still at the start, through talking a proposal through until it holds, to a transformation so visible it needs no explanation.
The judgment combines four positive terms—origination, success, beneficial steadfastness, and vanished regret—and the commentary strongly affirms Tang and Wu's revolutions as responding to Heaven and people. The fourth nine's sincere change of mandate and the fifth's tiger-like transformation with trust even before divination are powerful favorable lines. Yet risks are explicit: the third warns against rash advance, the top against continuing to push after change, and the first demands restraint at the outset. Conditions and legitimacy may suffice, but timing and trust strongly determine success, hence the rating: Rather Good, rather than the best. This is the app's interpretation of the text, not a guarantee of outcomes.
Worth doing: establish the reasons and the trust first, then replace the old arrangement in stages. Avoid: overturning everything before the timing is clear, or changing the label while the problem stays.
Understand This Hexagram Through Its Structure
Dui above, Li below: fire beneath a lake — opposing elements producing change.
- Name the upper and lower trigram of Ge.
- Explain why fire and lake together read as change.
- Work out that Change with its halves swapped is Divergence.
The lower trigram of Ge is Li: solid, broken, solid. The upper is Dui: two solid lines with a broken sixth. The first, third, fourth and fifth lines are solid.
Fire burns upward and water runs down; placed together, neither can stay as it was, so this hexagram reads as change. It does not say change is good, but that in this structure keeping things as they are costs more than changing them. Note that ge means a structural replacement, not a patch.
A teaching example, not a prediction: a process needs manual repair every time, and keeping it going now costs more than redesigning it. Ge describes that structure; it does not say the redesign succeeds.
The Six Lines: Original Text and Reflection
Nine at the beginning: Bound fast with yellow oxhide.
The Xiang commentary says that being bound with yellow oxhide means there is nothing to be done yet. At the lowest position and the first moment of change, self-restraint is the whole of the task.
You are strapped tight with tough oxhide. Change has only just begun, your position is the lowest and your leverage the least. What this stage asks is not action but holding yourself still.
The moment you first see what is wrong is the moment you most want to announce it everywhere. Keep it in, stay steady, and speak when you carry enough weight for it to land.
Do you carry enough weight yet to change the thing you are itching to change?
Six in the second place: On the si day, make the change. Advancing brings good fortune and no blame.
The Xiang commentary says that changing on the appointed day means the action itself carries something good. Timing and legitimacy have lined up, so going forward is favourable and no fault follows.
You act only when the day has come, and going forward is favourable with no fault. The same move a step early is recklessness and a step late is a missed chance. It holds only on the day it fits.
A change you have put off for a long time is usually waiting for the moment when not changing costs more. Once that moment arrives, say the thing and make the swap. Hesitating closes the gap that finally opened.
Has the right moment you are waiting for already arrived?
Nine in the third place: Advancing brings misfortune; steadfastness brings danger. When talk of change is affirmed three times, there is trust.
The Xiang commentary asks where else there is to go once the case for change has been through three rounds. The argument has been aired fully; what remains is to settle it and act, not to press further forward.
Forcing your way forward brings danger, and even holding correct carries risk. But if the case has been debated three times over and consensus has formed, you have a foundation of good faith. Pushing does not work here. Talking it through does.
When your proposal gets challenged, the worst response is to treat the objection as an obstacle and push harder. Take the same case to three different rooms, absorb the objections, revise. Resistance afterwards is far smaller.
How many times has your proposal genuinely been argued through?
Nine in the fourth place: Regret vanishes. With sincerity, change the mandate. Good fortune.
The Xiang commentary says the good fortune of changing the mandate rests on the will being trusted. Good faith has to be established first; only then does altering the old order hold.
Regret disappears. Carrying trust you have already built, you alter the established rules, and the line reads well. What lets you change the mandate is not the authority itself but other people believing in your intent.
The people who actually manage to replace an old rule are usually the ones who first convinced everyone they were not doing it for themselves. With trust in place, a large move is accepted. Without it, even a small adjustment looks like a grab for power.
Who do the people around you believe this change is for?
Nine in the fifth place: The great person transforms like a tiger. Trust exists before divination.
The Xiang commentary says the great person changes like a tiger because the markings are brilliant. The transformation has become so plainly visible that no divination is needed for people to trust it.
The person at the centre is renewed the way a tiger renews its coat, markings sharp and unmistakable, and trust is there before anyone consults the oracle. Change made thoroughly enough speaks for itself.
When someone's transformation is large enough to be seen at a glance, they no longer have to spend energy explaining that they have changed. Rather than repeating your resolve, make the change clear enough that no statement is required.
Can anyone actually see the change you keep describing?
Six at the top: The noble person transforms like a leopard; the petty person changes the face. Advancing brings misfortune; remaining steadfast brings good fortune.
The Xiang commentary says the noble person changes like a leopard, with fine dense markings, while the small person changes only the face, going along with whoever is above. The second is compliance, not inward change.
At the closing stage of change, some renew themselves thoroughly while others merely adjust their expression and follow the crowd. Pressing further forward brings danger; settling down and holding correct is favourable.
As a reform winds down, some people have genuinely changed their minds and others have simply stopped objecting. You do not need everyone to declare agreement. Bedding the new arrangement into ordinary routine does more than pushing harder.
Has this change reached the point where it should be brought to a close?
