Master Kyogen said, “It is like a man up a tree who hangs from a branch by his mouth; his hands cannot grasp a bough, his feet cannot touch the tree.
Another man comes under the tree and asks him the meaning of Bodhidharma’s coming from the West. If he does not answer, he does not meet the questioner’s need. If he answers, he will lose his life. At such a time, how should he answer?” (Gateless Gate, Case 5)
