One day, a Sutra Master came and he questioned Zen Master Dae-Ju. "I understand that you
have attained Satori. What is Zen?'"
Dae-Ju said, "Zen is very easy. It is not difficult at all. When I am hungry, I eat; when I am
tired, I sleep."
The Sutra Master said, "This is doing the same as all people do. Attaining satori [Zen enlightenment] and not attaining are then the same."
"No, no, most people are different on the outside than on the inside.'"
The Sutra Master said, "When I am hungry, I eat. When I am tired, I sleep. Why is the outside different from the inside?"
Dae-Ju said, "When most people are hungry, they eat. Only the outside, the body, is eating. On the inside they are thinking, and they have desire for money, fame, sex, food, and they feel anger. And so when they are tired, because of these wants, they do not sleep. So, the outside and the inside are different. But when I am hungry, I only eat. When I am tired, I only sleep. I have no thinking, and so I have no inside and no outside."
