Hexagram 49: Ge (革)

Bind it fast with the hide of a yellow ox. Hold the change in place before it begins. Changes into Hexagram 31 (Xian).

The very first line, and it is about restraint rather than action. A yellow ox is the strongest, most placid animal available and 巩 means to consolidate or wall up. The instruction is to fasten the material down while it is still raw - leather cannot be reshaped once it has set. If this is your line, the change you are contemplating has to be prepared and held, not launched; the mistake being avoided is the one where the new form is committed to before anyone has confirmed it will hold.

On the appointed day it is changed; to move out then is good, and there is no blame. The single permitted moment of action. Changes into Hexagram 43 (Guai).

This is the line that acts, and it is precise about when. 六二 does not open with 征 (march) but conditions it - on the day named in the judgment, and not before. The soft line holding the middle position is neither a leader nor a follower but the person who waits for the credible moment and uses it. If this is your line, the answer is yes, and the answer comes with a date: what you are waiting for is not permission but confirmation that the ground has actually changed.

To march out is bad, and constancy here is dangerous. The words of change must be gone over three times; then there is belief. Changes into Hexagram 17 (Sui).

The line that stops a plan that is right but premature. 革言三就 means the proposal gets argued and re-argued until it has been tested three times, and only then does it have 孚. 贞厉 is the sharper warning: holding firm in the wrong moment is itself dangerous, because rigidity is just change frozen too early. This is the line to work from if you are mid-reform and feeling pressure to finish - the hexagram says the discipline is in the third round of questions, not in the announcement.

Regret disappears. There is belief, and the mandate is changed; good. Change the terms, not just the appearance. Changes into Hexagram 63 (Ji Ji).

The most encouraging line in the hexagram, because regret is what usually accompanies change and here it is cancelled. The mechanism is 有孚改命 - a mandate altered once it has earned credibility, which is a different transaction from persuading anyone to agree with you. 九四 is the position closest to power without being the leader, so the line describes the moment when a decision you had been stuck on becomes both permitted and correct. If this is your line, the blocker was never the other people; it was that the case had not yet been made.

The person of standing changes like a tiger; there is no need to divine, for it is already believed. Changes into Hexagram 55 (Feng).

The tiger is not metaphor here but the classical emblem of the ruling power, and 未占有孚 says it does not even need to be tested - the change is visible in the person rather than argued in the argument. This is the hexagram at its most confident, and it describes authority that has genuinely transformed and is simply observed to have done so. The risk implied is the obvious one: a leader who has changed does not need to check, which is exactly the position where checking gets skipped.

The noble person changes like a leopard; the small person changes only their face. To march out is bad; to hold correctly is good. Changes into Hexagram 13 (Tong Ren).

The closing line separates the two kinds of change, and it is not kind. A leopard changes in visible, distinctive markings; the small person 革面 changes only the surface, keeping everything else. The judgment is that the second kind is the more dangerous one, because it looks like reform from outside. 上六 is the top position, so the warning arrives late and is about stopping: 征凶, moving on from here is bad, and the answer is 居贞吉, stay put and hold correctly.
