"Physical intelligence naturally avoids what is toxic and approaches what is nourishing. It is only by being out of touch with our basic instincts that this natural tendency is reversed; we avoid nourishment and are attracted to the toxic. There is nothing particularly ‘WRONG’ with this until we fail to see the long-term implications of self-destructive tendencies. Physical intelligence is sharpened through hunger, ask any dancer. There is a saying in Zen which demonstrates this kind of body wisdom: ‘Eat when you are hungry, sleep when you are tired and wake up when you stop dreaming.’ What could be more simple?"
