Trigram Ch'ien, the Creativeabove Ch'ien the Creative, Heaven
Trigram Tui, the Joyousbelow Tui the Joyous, Lake

The name of the hexagram means on the one hand the right way of conducting oneself. Heaven, the father, is above, and the lake, the youngest daughter, is below. This shows the difference between high and low, upon which composure correct social conduct, depends. On the other hand the word for the name of the hexagram, Treading, means literally treading upon something. The small and cheerful (Tui) treads upon the large and strong (Ch'ien). The direction of movement of the two primary trigrams is upward. The fact that the strong treads on the weak is not mentioned in the Book of Changes, because it is taken for granted. For the weak to take a stand against the strong is not dangerous here, because it happened in good humor (Tui) and without presumption, so that the strong man is not irritated but takes it all in good part.
