THE SIGN:

Trigram Kên, Keeping Stillabove Kên Keeping Still, Mountain
Trigram Kên, Keeping Stillbelow Kên Keeping Still, Mountain

The image of this hexagram is the mountain, the youngest son of heaven and earth. The male principle is at the top because it strives upward by nature; the female principle is below, since the direction of its movement has come to its normal end.
In its application to man, the hexagram turns upon the problem of achieving a quiet heart. It is very difficult to bring quiet to the heart. While Buddhism strives for rest through an ebbing away of all movement in nirvana, the Book of Changes holds that rest is merely a state of polarity that always posits movement as its complement.
Possibly the words of the text embody directions for the practice of yoga.
