Nourish by what is rightMouth Corners
What you feed on is what you become.
Yi is two mouths, above and below, with emptiness between — every life depends on the rhythm of input and output. Nourishment here is not only food but everything that shapes you: information, relationships, habits, ideas. Fed wrong, effort itself becomes consumption; fed right, ordinary things grow strength. Yi also hints: the skill of closing the mouth is harder to learn than opening it.
The image says it plainly: be careful in speech, temperate in food and drink. One in, one out — hold both mouths and a person stands. Many labor to choose what goes in yet never choose what goes out — though the latter shapes you more.
