Zhouyi BenyiJudgment
Gèn (hexagram-52) means stopping. A single yang line stops above two yin lines; yang ascends from below, reaches the very top, and halts.
Its image is the mountain, taking the earth of Kūn (hexagram-2) and raising it high above, which also carries the meaning of stopping at the peak and not advancing further.
Its divination indicates that one must be able to stop at one's back and not possess one's body, and walk in one's courtyard without seeing one's people, only then being without blame. The body is a moving thing; only the back is at rest.
Keeping one's back still means stopping where one ought to stop. Stopping where one ought to stop means not moving along with the body; this is what it means not to possess one's body.
If one can do this, then even walking through the courtyard where people reside, one will not see anyone. Keeping one's back still and not possessing one's body means stopping when it is time to stop.
Walking in one's courtyard and not seeing one's people means remaining still even while moving. Both movement and stillness each stop in their proper place, and both take stillness as their master; this is why one obtains 'without blame.'
