Ma-tsu is reported in the chronicles to have had 139 enlightened disciples, many of whom went on to become Ch'an leaders in their own districts. The most outstanding were the monks Huai-hai and Nan-ch'uan and a layman named P'ang--all three of whom are today remembered in anecdotes that have become Ch'an scriptures. But others were probably just as active and enlightened. Southern Ch'an was expanding, with mountaintop retreats blossoming everywhere. Many teachers probably have been forgotten only because they had no disciples who took the pains to transcribe and preserve their teachings. Ma-tsu himself also apparently wrote nothing, but he was more fortunate in his disciples. In any case, he reportedly died in the typical Ch'an way. He predicted his death a month in advance, and when the time came, he bathed, assumed the meditation posture, and silently passed on. Chapter Seven HUAI-HAI: FATHER OF MONASTIC CH'AN Among the many celebrated disciples of Ma-tsu, the man whose influence has been most pervasive throughout the succeeding centuries was Po- chang Huai-hai (720-814). He is the master credited with founding the first wholly Ch'an monastery, with devising a special set of rules for Ch'an discipline, and with writing a closely argued treatise on sudden enlightenment. Whereas Ma-tsu and others of his disciples such as Nan- ch'uan experimented with ways to help novices break through the barrier of reason, Huai-hai examined the phenomenon of enlightenment itself and described the mental state of preparedness necessary to reach the Other Shore. Huai-hai has been somewhat unjustifiably neglected by the modern Zen movement, perhaps because his expository style did not lend itself to memorable anecdotes or koan cases. The accounts of Huai-hai's origin are contradictory, but he seems to have begun his Buddhist studies early, becoming the pupil of a master named Tao-chih in a small town in the present-day province of Chekiang.1 (It was this master who gave him the religious name Huai-hai, or "Ocean of Wisdom.") After he came to maturity, the story goes, he heard of the great master Ma-tsu in the province of Kiangsi, and he traveled there to study. Among the many anecdotes surrounding Huai-hai's stay with Ma-tsu, perhaps the finest is that of the auspicious first encounter. The story says that when Huai-hai arrived, the old master immediately asked what previous temple he had traveled from, followed by: "What do you come here to find?" Huai-hai replied, "I have come to discover the truth of Buddha." To this Ma-tsu replied, "What can you expect to learn from me? Why do you ignore the treasure in your own house and wander so far abroad?" Understandably puzzled, Huai-hai asked, "What is this treasure that I have been ignoring?"
