Yang Chu (440-360 B.C.), Garden of Pleasure
, tr. Anton Forke (New York: E.P. Dutton and Company, 1912), p. 43 (beginning of Chapter VIII):
Yen-Ping-Chung asked Kuan-Yi-Wu as to cherishing life.
Kuan-Yi-Wu replied: "It suffices to give it its free course, neither checking nor obstructing it."
Yen-Ping-Chung said: "And as to details?"
Kuan-Yi-Wu replied: "Allow the ear to hear what it likes, the eye to see what it likes, the nose to smell what it likes, the mouth to say what it likes, the body to enjoy the comforts it likes to have, and the mind to do what it likes."
