" Once Zen Master To An was visiting another temple. He wasn't wearing his Zen Master clothes, only the clothes of a wandering monk. He began a conversation with one of the monks at the temple, who did not recognize that he was a Zen Master. Soon the monk began to talk about his Master. “Every day he does one thousand prostrations. He eats only once a day. He hasn't left the temple for thirty years. He is always sitting Zen. He is the greatest Zen Master in all of China.” To An said, “Well well, he sounds like an extraordinary man. I can't do any of these things. I can't bow a thousand times a day; but my mind is never lazy. I can't eat only once a day; but I never desire food. I can't stay in a temple for more than a short time; but wherever I go I have no hindrance. I can't sit Zen for very long; but I never give rise to thinking.” The monk said, “I don't understand.” To An said, “Go ask your Master to explain.” The monk bowed and went into the temple. Soon the Zen Master came running out to To An and prostrated himself three times in front of him. “You are a great Zen Master,” he said. “Please let me become your disciple. I have been very attached to hard training. But now that I have heard your kind words, my mind is clear.” To An laughed and said, “No no, I can't be your teacher. You are already a great Zen Master. All you need to do is to keep the mind you had when you were bowing to me. Already you are a free man. Before, you were bowing, sitting, and eating only for yourself. Now it is for all people.” At these words, the Zen Master began to weep with joy. He bowed again to To An and said, simply, “Thank you. "
