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?"
To which came the celebrated reply: "The one who questions me at this moment is your treasure. Everything is complete in it. It is lacking in nothing, and furthermore the things it possesses are inexhaustible. Considering that you can use this treasure freely, why then do you persist in wandering abroad?" It is said that with these words Huai-hai suddenly had an intuitive, non-rational acquaintance with his own mind.2
Among the other classic tales of Huai-hai's apprenticeship under Ma-tsu is the often repeated account of the day the two of them were walking together along a path when suddenly a flock of migratory geese was heard passing overhead. Ma-tsu turned to his pupil and asked, "What was that sound?" Huai-hai innocently replied, "It was the cry of wild geese." Ma-tsu paused and then demanded of his pupil, "Where have they gone?" Huai-hai said, "They have flown away."
This was an unacceptably drab, straightforward answer for a Zen man, and in disgust Ma-tsu whirled, grabbed Huai-hai's nose, and twisted it until his disciple cried out in panic, causing Ma-tsu to observe, "So you thought they had flown away. Yet they were here all the time."3
The legends say that this exchange, in the typical harsh style of Ma-tsu, caused Huai-hai to confront his original nature. What Ma-tsu had done was to give his pupil a vivid lesson in the concept of an indivisible unity which pervades the world; things do not come and go—they are there always, part of a permanent fabric. Huai-hai was being invited to stop viewing the world as a fragmented collection of elements and see it rather as a unified whole.
The interactions of master and novice were always dynamic. For example, another story says that one day Ma-tsu asked Huai-hai how he would teach Ch'an. Huai-hai responded by holding up a dust whisk vertically. Ma-tsu continued by asking him, "Is this all there is? Is there nothing more?" Huai-hai replied by throwing down the whisk. (One interpreter has said that raising the dust whisk revealed the mind's function, whereas throwing it down returned function to the mind's substance.)4 According to some versions of this episode, Ma-tsu responded by shouting at the top of his lungs, rendering Huai-hai deaf for three days. This shout is said to have been the occasion of Huai-hai's final enlightenment.
