157. There is an old zen story that says 'it' is like a man up in a tree who is hanging from a branch by the skin of his teeth. His hands can't get hold of a bough, his feet can't find a limb to stand on. Then someone standing on the ground below him calls out, 'What is the meaning of Bodhidharma coming from the West?' It is said that if he does not answer he fails to respond to the question whereas if he does answer he will lose his life. It seems that I'm in that situation. What to do?
