|1.||a Japanese school, of 12th-century Chinese origin, teaching that contemplation of one's essential nature to the exclusion of all else is the only way of achieving pure enlightenment|
|2.||(modifier) of or relating to this school: Zen Buddhism|
|[from Japanese, from Chinese ch'an religious meditation, from Pali jhāna, from Sanskrit dhyāna]|
An approach to religion, arising from Buddhism, that seeks religious enlightenment by meditation in which there is no consciousness of self.
Note: Deliberately irrational statements are sometimes used in Zen to jar persons into realizing the limits of the common uses of the intellect. One well-known example is, “What is the sound of one hand clapping?”
