Mumonkan - Case 27: It is Not Mind, It is Not Buddha, It is Not Things A monk asked Nansen: "Is there a teaching no master ever preached before?" Nansen said: "Yes, there is." The monk asked: "What is it?" Nansen replied: "It is not mind, it is not Buddha, it is not things." Mumon's Comment: Old Nansen gave away his treasure-words. He must have been greatly upset. Nansen was too kind and lost his treasure. Truly, words have no power. Even though the mountain becomes the sea, Words cannot open another's mind.
