. . . . in which teachers of rural, Southern Ch'an begin to experiment with new ways to precipitate the "sudden" enlightenment experience, even bringing into question the role of meditation. Along with the search for new techniques goes the attempt to define precisely what enlightenment is and to formalize the transmission process. During this time, Ch'an monasteries become independent organizations and Ch'an a recognized, if eccentric, Buddhist sect. The iconoclastic, self- supporting Ch'an establishments ride out a persecution of Buddhism in the mid-ninth century that effectively destroys all other Buddhist schools in China. This is the great creative era of Ch'an, in which the sect secures its own identity and creates its own texts for use by later generations. Chapter Six MA-TSU: ORIGINATOR OF "SHOCK" ENLIGHTENMENT _Ma-tsu (right) and Layman P'ang_ If Hui-neng was the Sixth Patriarch, then who was the seventh? Although several of his followers are mentioned in the Platform Sutra, the only one who seems to have made any difference in Ch'an history was Shen-hui (670-762), who successfully destroyed the Northern school of Shen-hsiu (605-706) and elevated Hui-neng. Although Shen-hui was given the accolade of Seventh Patriarch in some parts of the north, history was to be written elsewhere. Shen-hui's school of "Southern" Ch'an was soon compromising with the remaining Northern Ch'anists--conceding that the study of the sutras could go along hand in hand with sudden enlightenment--and he seems to have enjoyed a little too much his role as imperial socialite. The only member of Shen-hui's school to realize any historical prominence was Tsung-mi (780-841), whose fame attaches not to his original thought but rather to his scholarly writings describing the various sects of Ch'an.1 A litterateur and friend of the famous poet Po Chu-i (772-846), he also tried unsuccessfully to mediate between the followers of the step-by-step sutra-reading Buddhists of the cities and the all-at-once, anti-literary proponents of sudden enlightenment in the country, but he succeeded only in bringing the history of Northern Ch'an to a dignified close.2
