The system is too sensitive and shows symptoms which are startlingly like human anxiety. For when a human being is so self-conscious, so self-controlled that he cannot let go of himself, he dithers or wobbles between opposites. This is precisely what is meant in Zen by going round and round on “the wheel of birth-and-death,” for the Buddhist samsara is the prototype of all vicious circles.
