The Six Lines

Line 1: Line 1: Mighty in the forward-striding toes. When one goes and is not equal to the task, one makes a mistake.

Line 2: Line 2: A cry of alarm. Arms at evening and at night. Fear nothing.

Line 3: Line 3: To be powerful in the cheekbones brings misfortune. The superior man is firmly resolved. He walks alone and is caught in the rain. He is bespattered, and people murmur against him. No blame.

Line 4: Line 4: There is no skin on his thighs, and walking comes hard. If a man were to let himself be led like a sheep, remorse would disappear. But if these words are heard, they will not be believed.

Line 5: Line 5: In dealing with weeds, firm resolution is necessary. Walking in the middle remains free of blame.

Line 6: Line 6: No cry. In the end misfortune comes.

Modern Application

Hexagram 43 represents the decisive moment when accumulated pressure breaks through. The lake risen to heaven is an image of water suspended unnaturally — it must fall. This is the hexagram of confronting evil or corruption and making a clean break. The judgment emphasizes that the matter must be announced truthfully, not settled by force (arms). The superior person resolutely faces what must be faced, dispensing rewards afterward rather than resting on virtue. In modern terms, Breakthrough applies to whistleblowing, ending toxic relationships, making difficult decisions, and the moment of truth when evasion is no longer possible.
