Why does the text say “the top of the comb breaks off”? This line statement carries three layers of meaning that unfold simultaneously.

The first layer is the literal image. This hexagram is about combing hair; the top of the comb breaks off, and it can no longer be used. The instrument of scrutiny itself is destroyed.

The second layer concerns the Qian side. Qian represents the head being combed, while Zhen represents what needs to be combed out and removed. The Hidden Hexagram changes into a Zhen-Qian image, where Zhen and Qian now stand in the same position — the Zhen side can no longer be separated from the Qian side. If one insists on carrying out scrutiny and subduing the Zhen side by force, the entire head — the whole state — will be broken and destroyed along with the comb.

The third layer is that the comb itself is a metaphor for the Gen side. Its top breaking off means that the Gen side itself loses its head — its leadership is destroyed. Originally, the upper Li trigram of the Hidden Hexagram represented focal-player energy and the person carrying out scrutiny; it was formed by two half-Gen images stacked forward and backward. When the sixth line moves, the upper half-Gen within Li disappears, symbolizing the disappearance of Li’s leadership. The comb’s top breaks; the scrutiny official falls.

Why does the text say “disaster”? “Disaster” is spoken from the perspective of the focal player — the person who carries out combing and scrutiny. When the sixth line moves, the upper trigram of the Original Hexagram changes from Kan into Xun. Kan represents sectioning and scrutiny; Xun represents retreat and failure. Xun is stacked with the Gen trigram formed by lines three, four, and five, indicating the failure of the Gen side.

The Hidden Hexagram changes into Zhen over Qian, which carries two layers of meaning. First, Zhen as a noun can be understood as the other-player side, while Qian means victory: the other player wins. Since Zhen is also the reverse of Gen, this shows that the energy opposed to Gen achieves victory. Second, Zhen as a verb can mean taking the upper hand, while Qian represents the king or leader: the leader inclines toward the Zhen side and takes action against the Gen side. Moreover, in the Hidden Hexagram, the upper trigram changes from Li into Zhen. Li represents the eyes of the scrutiny side, the oversight mechanism, and the bonding relationship between the focal player and the king. Now it changes into other-player energy, showing that the Li side is suppressed by the other player and disappears. All these clues converge in the collapse of the focal-player energy. Therefore, the text says “disaster.”

As the final line of a hexagram, the sixth line often represents both the ending of the story and a reversal in the plot. From four perspectives, this sixth line inverts everything that came before. In the first five lines, the combing action proceeds step by step; in the sixth line, combing can no longer take place. In the first five lines, the Gen side, as the hair-combing person, clears away the Zhen side; in the sixth line, the Gen side itself is cleared away. In the first five lines, the Zhen side is the object being removed; in the sixth line, the Zhen side gains the upper hand. In the first five lines, the Qian side supports the Gen side; in the sixth line, the Qian side supports the Zhen side. The story of the incompetent hair-combing specialist reaches its grim conclusion.
