Virtually all the masters encountered up to this point have been traceable to Ma-tsu, descendant in Dharma of the legendary Huai-jang and his master, the Sixth Patriarch, Hui-neng. This was the line that became Japanese Rinzai Zen, many centuries later. However, Hui-neng had another follower, a shadowy figure remembered as Ch'ing-yuan Hsing-ssu (d. 740) whose line also was perpetuated to present-day Japan.1 His foremost pupil was Shih-t'ou (700-90), and a common description of the eighth-cen- tury Ch'an establishment was: "In Kiangsi the master was Ma-tsu; in Hunan the master was Shih-t'ou. People went back and forth between them all the time, and those who never met these two great masters were completely ignorant."2 Shih-t'ou jousted with Ma-tsu, and they often swapped students. Ma-tsu sent his pupils on their way with a wink and the advice that Shih-t'ou was "slippery."3 This legendary master was forebear of three of the five "houses" of Ch'an arising after the Great Persecution of 845, although the only one of the three surviving is the Ts'ao-tung, which arose during the later T'ang (618- 907) and early Five Dynasties (907-960) period and remains today as Japanese Soto. One of the cofounders of the Ts'ao-tung house was known as Tung-shan Liang-chieh (807-869), who was born in present day Chekiang but eventually found his way to what is now northern Kiangsi province.4 As did most great masters, he took Buddhist orders early, and one of the most enduring stories of his life has him confounding his elders--an event common to many spiritual biographies. He began as a novice in the Vinaya sect, an organization often more concerned with the letter of the law than its spirit. One day he was asked to recite the Heart Sutra, but when he came to the phrase "There is no eye, ear, nose, tongue, body, or mind," he wonderingly touched his own face and then inquired of his master, "I have eyes, ears, nose, tongue, and so forth; how, then, can the sutra say there are no such things?"5 The Vinaya master was dumbfounded by his iconoclasm and suggested that his bent of mind would be more readily cultivated in the Ch'an sect. So off he went to Mt. Sung, where he subsequently was ordained at the precocious age of twenty-one. Afterward he traveled across China, typical for young monks of the age. Ironically enough, considering that his line eventually rivaled Ma- tsu's, his first stop was the monastery of Nan-ch'uan, one of the foremost disciples of Ma-tsu. As he arrived, Nan-ch'uan was announcing a memorial service to be conducted the next day on the anniversary of his master's death, a standard Chinese custom.
