17. A study of the last distinguished member of Shen-hui's school, the scholar Tsung-mi (780-841), may be found in Jeffrey Broughton, "Kuei- feng Tsung-mi: The Convergence of Ch'an and the Teachings" (Ph. D. dissertation, Columbia University, 1975). 18. D. T. Suzuki, "Zen: A Reply to Hu Shih," Philosophy East and West, 3, 1 (April 1953), pp. 25-46. 19. 5. HUI-NENG: THE SIXTH PATRIARCH AND FATHER OF MODERN ZEN 1. A number of English translations of the Platform Sutra are in existence. Among the most authoritative must certainly be counted Yampolsky, Platform Sutra of the Sixth Patriarch; and Wing-tsit Chan, The Platform Scripture (New York: St. John's University Press, 1963). A widely circulated translation is in A. F. Price and Wong Mou-Lam, The Diamond Sutra and the Sutra of Hui-Neng (Berkeley, Calif.: Shambhala, 1969). Another well-known version is found in Charles Luk, Ch'an and Zen Teaching: Third Series (New York: Samuel Weiser, Inc., 1971). Two lesser-known translations are Paul F. Fung and George D. Fung, The Sutra of the Sixth Patriarch on the Pristine Orthodox Dharma (San Francisco: Buddha's Universal Church, 1964); and Hsuan Hua, The Sixth Patriarch's Dharma Jewel Platform Sutra (San Francisco: Buddhist Text Translation Society, 1971). 2. From the Diamond Sutra, contained in Dwight Goddard, ed., A Buddhist Bible (Boston: Beacon Press, 1970), p. 102. Another version may be found in Price and Wong, Diamond Sutra and the Sutra of Hui-neng. An extended commentary may be found in Charles Luk, Ch'an and Zen Teaching, First Series, pp. 149-208. Later Ch'anists have maintained that Hung-jen taught both the Diamond Sutra and the Lankavatara Sutra, the respective scriptures of what came to be called Southern and Northern schools of Ch'an. However, most scholars today believe that his major emphasis was on the Lankavatara Sutra, not the Diamond Sutra as the legend of Hui-neng would have. 3. From Price and Wong, Diamond Sutra and the Sutra of Hui-neng, p. 15. 4. Ibid., p. 18. 5. The earliest version of the Platform Sutra is that found in the Tun- huang caves and translated by Yampolsky and Chan. This manuscript Yampolsky dates from the middle of the ninth century. A much later version, dated 1153, was found in a temple in Kyoto, Japan, in 1934. This is said to be a copy of a version dating from 967. The standard version up until this century was a much longer work which dates from 1291. As a general rule of thumb with the early Ch'an writings, the shorter the work, the better the chance it is early and authentic. For this reason, the shorter Tun-huang works are now believed to be the most authoritative and best account of the thoughts of the Sixth Patriarch. 6.
