上乘禅
The Mahyna Ch'an (Zen) School, which considers that it alone attains the highest realization of Mahyna truth. Hnayna philosophy is said only to realize the unreality of the ego and not the unreality of all things. The Mahyna realizes the unreality of the ego and of all things. But the Ch'an school is pure idealism, all being mind. This mind is Buddha, and is the universal fundamental mind.
