The biographical record of the Tsung-men teachers in the Chi-yue-luh contains notices of priests trained by the predecessors of the sixth patriarch, and sent out to teach the doctrine of Bodhidharma. Two were instructed by the successor of Bodhidharma, eight by the fourth patriarch, and six by the fifth. One of the latter, Shin-sieu, was styled the sixth patriarch for North China, while Hwai-neng, the legitimate successor of Bodhidharma, from residing in the southern provinces, was called the sixth patriarch
for the South. Nothing is said of the schools originated in various provinces by these teachers. It is only the successors of Hwai-neng, the last-mentioned hierarch, that are regarded as deserving a memorial. From him a series of disciples, all becoming "teachers" (ch'an-si) in their turn, are counted to the sixteenth generation. This mode of expression is used instead of mentioning, according to custom, the years of imperial reigns and dynasties. The biography in the Chi-yue-luh, a book of the Ming dynasty, ceases at the sixteenth descent. This was at the beginning of the twelfth century, and the whole series embraces about four hundred years. Modern monks of these schools trace their succession in a similar manner, according to a more recent arrangement, in twelve divisions. The reason for this careful record of ecclesiastical ancestry is to be sought in the principle of unbroken lineal descent, which is indispensable to the maintenance of esoteric tradition. Yet it does not appear that there was any secret doctrine which those who knew it would not divulge. What they held was simply a protest against the neglect of the heart, and dependence on book knowledge and the performance of outward rites. Since their object was to draw neophytes away from the inordinate study of the books of the religion, instruction was given orally. An extensive series of works containing records of the instructions of these teachers has been the result. They are called Yu-luh, "Records of the sayings" of celebrated teachers.
Several branch schools were originated by the successors of the sixth patriarch. In the fourth generation from him the Hwei-niang school was formed. In the fifth appears that of Lin-tsi and Ts'au-tung. The Yun-men belongs to the eighth generation. That called Fa-yen belongs to the ninth. These names are taken from the places where the founders of the respective schools resided. They are denominated collectively the Wu-tsung, or "Five schools," to distinguish them from those which preceded them, and adhered more closely to the tradition of the patriarchs.
