a yellow square, indicating this line as the constituting ruler of the hexagram Six at the top means:

Seductive joyousness.

A vain nature invites diverting pleasures and must suffer accordingly (cf. the six in the third place). If a man is unstable within, the pleasures of the world that he does not shun have so powerful an influence that he is swept along by them. Here it is no longer a question of danger, of good fortune or misfortune. He has given up direction of his own life, and what becomes of him depends upon chance and external influences.
