Guai · Breakthrough
Cut cleanly, but argue in the open instead of forcing it.
Judgment and Plain-Language Notes
Guai: Declare it in the royal court. Call out sincerely. There is danger. Announce it from your own town. Resorting to arms is unfavorable; proceeding is beneficial.
The Tuan commentary glosses Guai as decision, the firm parting from the yielding, and asks for strength that stays agreeable and decisiveness that stays harmonious. Proclaiming it in the royal court and calling out in good faith while knowing the danger is what makes the conduct shine; force is ruled out because relying on arms runs to a dead end. The Xiang image is the marsh risen above heaven, with the noble person extending pay and favour downward rather than hoarding virtue.
Dui above, Qian below. Five firm lines press upward and only one yielding line remains at the top, so this is the clearing away of a last entrenched problem. Guai means to decide and to cut out. The judgement asks you to state the matter openly, to call out sincerely, and to be clear-eyed about the risk, and it says plainly that force is not favourable. The lines run from a premature advance that cannot win, through hardness worn on the face, an impasse where advice is refused, a measured decision in the centre, and finally a position with no one left to call to.
Although the judgment allows beneficial proceeding, it also explicitly warns of danger and against resorting to arms. The first nine's blame in unsuccessful advance, third's misfortune from forcefulness in the cheekbones, fourth's refusal to trust advice, and top's eventual misfortune without an outcry are negative. Only the second's “do not worry” and fifth's blameless middle path offer balance. Misfortune and blame outweigh good fortune, hence the rating: Poor. This is the app's interpretation of the text, not a guarantee of outcomes.
Worth doing: state the decision and the reasons publicly, and act firmly while keeping a safety margin. Avoid: settling scores privately, pushing people by force, or staking everything while the risk is still unclear.
Understand This Hexagram Through Its Structure
Dui above, Qian below: five solid lines rising, with only the topmost broken.
- Name the upper and lower trigram of Guai.
- Say why the broken line at the top is decisive.
- Work out that Resolute Parting with its halves swapped is Treading.
The lower trigram of Guai is Qian, all solid; the upper is Dui, solid at the fourth and fifth and broken at the sixth. Only the sixth line is broken; the five beneath are solid.
Five solid lines have pushed up to the fifth place, leaving one yin line at the top. Structurally this reads as resolute parting: one step from clearing it, and that last step is where things go wrong, precisely because the force behind is so complete. The cautions attached to this hexagram all live here — near the end, rushing to finish is more dangerous than the remaining resistance.
A teaching example, not a prediction: only the final sign-off remains and everything before it has passed; this is exactly when a check is skipped out of haste. Guai describes that structure.
The Six Lines: Original Text and Reflection
Nine at the beginning: Strength in the forward toes. Going without prevailing brings blame.
The Xiang commentary says bluntly that going forward when you cannot prevail is itself the fault. Strength shown in the front toes is strength shown too early.
The foremost toe pushes off first, the advance cannot win, and that is where the fault lies. Stepping out ahead from the lowest position with strength still short means you carry the risk alone.
Leading a confrontation before you have the capability or the backing rarely holds. Weigh your actual odds before deciding to be the first voice in the room.
Are the odds on this move ones you have assessed, or ones you are hoping for?
Nine in the second place: An alert outcry. There are armed threats at night. Do not worry.
The Xiang commentary attributes the calm to holding the middle way: even armed trouble at dusk brings no need for worry, because the warning went out and the centre was kept.
Stay alert and raise the alarm, and even if something does break out in the night there is no need for excessive worry. Holding the centre and preparing in advance stops an incident turning into a disaster.
When you sense a risk, warn the people it touches and get ready. If it does arrive you have a response, which is far lighter work than scrambling afterwards.
Have you told the people who need to know about the risk you already sense?
Nine in the third place: Strength in the cheekbones brings misfortune. The noble person resolves resolutely, walking alone and meeting rain. Though soaked and resented, no blame.
Hardness shown in the cheekbones brings misfortune, yet the Xiang commentary says the noble person who is resolute and resolute again ends without fault, even when walking alone into rain and drawing resentment for being soaked.
Hardness worn on the face invites trouble. Yet the genuinely decisive person, walking alone, caught in the rain and grumbled at, still ends without fault. The difference is whether the resolve is inward firmness or outward force.
A firm position does not require a hard manner. The decision you have to make can be made quietly, and being misread or criticised for a while does not undermine it if the direction is sound.
Does your resolve show in your face, or in how you actually work?
Nine in the fourth place: No skin on the buttocks; walking falters. Leading the sheep makes regret vanish, but hearing advice, one does not believe it.
The Xiang commentary blames the hesitant gait on an unsuitable position, and the refusal to believe good counsel on hearing that is not clear. Leading the sheep would let the regret pass, but the advice is not taken.
Restless where he sits and hesitant where he walks. Going along with things the way one leads a sheep would clear the regret, but he hears the counsel and does not believe it. The problem is not the absence of warning but the inability to take it in.
When you are stuck between advancing and retreating, other people's suggestions are usually the way out. Rejecting every piece of advice is normally a sign that you are no longer judging clearly.
Whose advice did you dismiss recently without even considering it?
Nine in the fifth place: Resolutely remove the purslane. Walking the middle path brings no blame.
Clearing soft weeds with resolve upon resolve, holding the middle way, brings no fault. The Xiang commentary still adds that the centre is not yet fully bright, so a reservation remains.
Clear away what is soft and entangling with a decided hand, and holding the middle keeps you free of fault. But the commentary adds that the centre is not yet radiant: the handling is right without being admirable.
Deal with what needs clearing through proper channels, so the method stands up to scrutiny. At the same time, accept that this round may not have been elegant, and leave room to review it.
Would the way you handled this hold up if you had to explain it in public?
Six at the top: No outcry. Misfortune in the end.
The Xiang commentary says the misfortune of having no one to call to lies in a position that cannot last. Isolation at the top removes every answering voice.
There is no call left to make and the ending is unfavourable. Standing alone at the very top with nothing answering is the hexagram's closing warning: the situation can no longer be held.
Long before you reach the point where there is nobody to ask for help, repair the relationships and say the things that need saying. Read this as a description of the situation, not a prediction.
If something went wrong today, who could you actually turn to?
