What is Hexagram 43, Breakthrough?

Hexagram 43, Breakthrough (夬 Guài), is built from Lake (兌 Duì) over Heaven (乾 Qián), and the Wilhelm-Baynes translation reads its themes as breakthrough, truth, resolution. The classical sources describe it as a pattern in the Book of Changes (易經 Yìjīng), a situation to recognise, not a verdict to obey.

The judgment

The Judgment

Breakthrough. One must resolutely make the matter known at the court of the king. It must be announced truthfully. Danger. It is necessary to notify one's own city. It does not further to resort to arms. It furthers one to undertake something.
The image

The Image

The lake has risen up to heaven: the image of Breakthrough. Thus the superior person dispenses riches downward and refrains from resting on virtue.

Master Wei Lin's Interpretation

Interpretation by Master Wei Lin, Chinese Metaphysics Scholar, pattern recognition, not fortune-telling

The lake has risen to heaven, the dam is about to break. Breakthrough comes after long accumulation of pressure. Something decisive is happening. The I-Ching counsels: speak the truth clearly, even when it's uncomfortable. But do it through proper channels, not through force. The breakthrough you need may be as simple as finally saying what needs to be said.

The moving lines

The Six Lines

When a changing line appears in your reading, its text carries special guidance for your situation.

Line 1 (bottom)

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

Line 2

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

Line 3

To be powerful in the cheekbones brings misfortune. The superior person is firmly resolved. The one walks alone and is caught in the rain. The one is bespattered, and people murmur against the one. No blame.

Line 4

There is no skin on the thighs, and walking comes hard. If one would let oneself be led like a sheep, remorse would disappear. But if these words are heard, they will not be believed.

Line 5

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

Line 6 (top)

No cry. In the end misfortune comes.
