Foyan said, "I say there are but two types of sickness. One is to ride a donkey to look for a donkey. The other is riding a donkey and not let yourself get off of it. Don't you see that riding a donkey to find a donkey is a fatal disease? This old mountain monk is telling you, don't seek it! Clever people understand right where they are. They give up the 'seeking' disease and the crazy, thought pursuing mind. Once you've seen the donkey, not allowing yourself to get off it - now that is a disease that is most hard to cure. This old mountain monk is telling you, don't ride it!
"You are the donkey! The great Earth is the donkey! How are you going to ride it? If you continue to ride it you'll never cure this disease. If you don't ride it then all the worlds in the ten directions are opened to you. If you can get rid of both of these diseases at once, then there's nothing left in your mind, and you are called a person of the way. What could trouble you?
"Therefore, Zhaozhou asked Nanquan, 'What is the way?' and Nanquan answered, 'Everyday mind is the way'."
