The Three Treasures

Ears, eyes, and mouth are the three treasures:
shut them, and let nothing pass through.
The True Man withdraws in the depths of the abyss;
drifting and roaming, he keeps to the compass.

Watch and listen while wheeling around,
and opening and closing will always accord.
Take this as your lynchpin,
and movement and quiescence will never be exhausted.

The Breath of Li ☲ (eyes) strengthens and guards you within,
and Kan ☵ (ears) is not employed for listening.
Dui ☱ (mouth) is closed and not used for talking:
you follow the boundless with inaudible words.
