The twinkling of the eyes, the lifting of a finger or the thrusting out of the tongue may appear trivialities, but in the eyes of the Zen master they are just as grave, serious, and tremendous as the shaking of the earth or the bursting of the heavenly bodies. A mysterious light flashes in the sky and tens of thousands of human lives instantly vanish out of existence.
