A group of travelers came to visit Achaan Chah with three elegant questions: Why do you practice? How do you practice? What is the result of your practice? They were sent as a delegation by a European religious organization to ask these questions to a series of great masters throughout Asia.
Achaan Chah closed his eyes, waited, and then answered with three questions of his own: Why do you eat? How do you eat? How do you feel after you have eaten well? Then he laughed.
Later, he explained that we already understand and that teaching has to direct students back to their own inner wisdom, to their own natural Dharma. Therefore, he had reflected the search of these men throughout Asia back to the greater search within.
