failed to see the meaning of this remark and earnestly implored to be instructed in the ultimate teaching of Buddhism. This was done, and Fa-jung became the founder of the Niu-t‘ou school of Zen Buddhism. Tao-hsin died at the age of seventy-two, A.D. 651. Hung-jên, 605–675, the fifth patriarch, came from the same province as his predecessor, Ch‘i Chou, now in the district of Fu-pei. His temple was situated in Wang-mei Shan (Yellow Plum Mountain), where he preached and gave lessons in Zen to his five hundred pupils. He is claimed by some to have been the first Zen master who attempted to interpret the message of Zen according to the doctrine of the _Vajracchedikā-sūtra_. Though I cannot quite agree with this view for the reason already referred to elsewhere, we can consider the fifth patriarch the beginning of a turning in the history of Zen, which opened up to a full view under the sixth patriarch, Hui-nêng. Until now, the Zen followers had kept quiet, though working steadily, without arresting public attention; the masters had retired either into the mountains or in the hurly-burly of the world where nobody could tell anything about their doings. But the time had at last come for a full proclamation of Zen, and Hung-jên was the first who appeared in the field preparing the way for his successor, Hui-nêng. * * * * * Besides this orthodox line of patriarchs, there were some sporadic expositors of Zen throughout the sixth and the seventh century. Several of them are mentioned, but there must have been many more such who were either altogether forgotten or not at all known to the world. The two best known are Pao-chih (died 514)[4.46] and Fu-hsi (died 569)[4.47]; and their lives are recorded in the _Records_ as “adepts in Zen but not appearing in the world though well-known at the time.” This is a strange phrasing, and it is hard to know definitely what “not appearing in the world” means. Usually it applies to one who does not occupy any recognised position in an officially registered monastery. But of those that are classed under this heading, there is one at least to whom the designation does not properly apply; for Chi-i was a great high priest occupying an influential ecclesiastical post in the Sui dynasty. Whatever this was, those recorded here did not belong to the orthodox Zen school. The Tendai (T‘ien-tai) followers object to see two of their Fathers Hui-szŭ and Chi-i mentioned as “adepts in Zen but not appearing in the world though well-known at the time.” They think that these two are great names in the history of their school and ought not to be so indifferently referred to in the records of the Zen masters. But from the Zen point of view this classification is justifiable for the reason that the Tendai, except its metaphysics, is another current of Zen started independently of the line of Bodhi-Dharma, and if this were allowed to take a more practical course of development, it should
