Moheyan

Heshang Moheyan () was a late 8th century Buddhist monk associated with the East Mountain Teaching. Moheyan (摩訶衍) is a brief translation of Mahayana in Chinese, so the name literally means a Mahayana monk. He became famous for representing Chan Buddhism in the so called "Council of Lhasa," a debate between adherents of the Indian teachings of "gradual enlightenment" and the Chinese teachings of "sudden enlightenment," which according to tradition was won by the "gradual teachings."

==Etymology== Hwashang is a Tibetan approximation of the Chinese héshàng "Buddhist monk (). This, in turn, comes from the Sanskrit title upādhyāya "teacher".
