THE SIGN:above Tui the Joyous, Lake
This hexagram is related in form and meaning to Pi, Holding Together (hexagram 8). In the latter, water is over the earth; here a lake is over the earth. But since the lake is a place where water collects, the idea of gathering together is even more strongly expressed here than in the other hexagram. The same idea also arises from the fact that in the present case it is two strong lines (the fourth and the fifth) that bring about the gather together, whereas in the former case one strong line (the fifth) stands in the midst of weak lines.
