THE SIGN:above Tui the Joyous, Lake
This hexagram, like sun, is one of the eight formed by doubling of a trigram. The trigram Tui denotes the youngest daughter; it is symbolized by the smiling lake, and its attribute is joyousness. Contrary to appearances, it is not the yielding quality of the top line that accounts for joy here. The attribute of the yielding or dark principle is not joy but melancholy. However, joy is indicated by the fact that there are two strong lines within, expressing themselves through the medium of gentleness. True joy, therefore, rests on firmness and strength within, manifesting itself outwardly as yielding and gentle.
