Fa-jung (594-657)

The founder of the Oxhead school of Chinese Ch'an Buddhism, named after its headquarters on Oxhead Mountain (Chinese, Niu-t'ou shan). During the time when the controversy between the Northern and Southern Schools (see Northern-Southern School Controversy) was at its height, he attempted to chart a new path that would reconcile the two. He stressed the need to develop both meditative concentration and wisdom in tandem, the first through meditation, the second through doctrinal and scriptural study. He also accepted the T'ien-t'ai doctrine that all phenomena whatsoever have the Buddha-nature (as opposed to the Southern School's insistence that only sentient beings enjoyed this).
