夬Guai.Breakthrough.
Lake rises above Heaven: pressure reaches the point of declaration. Guai concerns decisive removal, public clarity and confronting a persistent problem without allowing determination to collapse into aggression.
Make the problem visible, then remove it without becoming it.
Guai means deciding, breaking through or resolutely separating. A single yielding line remains above five firm lines: the issue is exposed, yet its position still demands care.
The Judgment calls for public announcement and honest warning while explicitly rejecting a premature resort to arms.
Lake above. Heaven below.
Creative force rises until the Lake can no longer contain it. Resolution must release pressure through truth and proportion.
Decide openly, remain alert and do not glorify force.
The governing proposition
夬：揚于王庭，孚號，有厲，告自邑，不利即戎，利有攸往。
Breakthrough. Declare it at the royal court. Call out sincerely; danger is present. Announce it within the city. Resorting to arms is not beneficial. It is beneficial to have somewhere to go.
Decision with harmony
夬，決也，剛決柔也。健而說，決而和。
Guai is decision: the firm removes the yielding. Strength joins with openness; resolution retains harmony.
Distribute benefit downward
澤上于天，夬；君子以施祿及下，居德則忌。
Lake above Heaven: Breakthrough. The cultivated person distributes benefit below and avoids hoarding virtue.

Work and leadership
Name the persistent problem publicly, establish support and act within legitimate authority.
Relationships
State the boundary clearly. Do not use righteous certainty to avoid proportion or dialogue.
Timing and decisions
Move when evidence, capacity and destination align—not merely when frustration peaks.
Guai is constructive when clarity removes corruption without multiplying conflict.
