Mouth Corners
Providing Nourishment
What you take in and what you give out are one discipline — food, speech and character alike.
Yi places Gen, keeping still, the mountain, above Zhen, the arousing, thunder, so that the motionless upper trigram sits over the moving lower one as the fixed upper jaw sits over the moving lower jaw in chewing. The whole figure, firm at top and bottom with four broken lines between, is read as the open corners of the mouth. The Judgement directs attention to what a man provides for others and to what he seeks to fill his own mouth with, extending nourishment from food to speech and to the cultivation of character. The Image has the superior man careful of his words and temperate in eating and drinking.
Light
Concerns right nourishment of body and mind, care in what is taken in and what is given out, and the duty of sustaining others as well as oneself.
Shadow
The lines warn of nourishment sought from the wrong quarter and of envy at what another is fed. Appetite indulged without measure is the fault of this hexagram, and careless speech is the same fault in another form.
