THE SIGN:

Trigram Sun, the Gentleabove Sun the Gentle, Wind, Wood
Trigram Tui, the Joyousbelow Tui the Joyous, Lake

The wind blows over the lake and stirs the surface of the water. Thus visible effects of the invisible manifest themselves. The hexagram consists of firm lines above and below, while it is open in the center. This indicates a heart free of prejudices and therefore open to truth. On the other hand, each of the two trigrams has a firm line in the middle; this indicates the force of inner truth in the influences they present.
The attributes of the two trigrams are: above, gentleness, forbearance toward inferiors; below, joyousness in obeying superiors. Such conditions create the basis of a mutual confidence that makes achievements possible.
The character of Fu ("truth") is actually the picture of a bird's foot over a fledgling. It suggests the idea of brooding. An egg is hollow. The light-giving power must work to quicken it from outside, but there must be a germ of life within, if life is to be awakened. Far-reaching speculations can be linked with these ideas.
