Ma-tsu probably knew by this time that he had been set up, but he had to follow through: "But how can you make a mirror by polishing a brick on a stone?" The celebrated answer was: "How can you become enlightened by sitting in meditation?" The point, driven home time and again throughout the eighth century, was that enlightenment is an active, not a passive, condition. And Ma- tsu himself was to become the foremost exponent of enlightenment as a natural part of life. Ma-tsu always made a profound impression on his contemporaries, and no small part may be attributable to his peculiar physical traits. As _The Transmission of the Lamp _describes him: _In appearance and bearing he was most striking. He glared as a tiger does and he ambled like a cow. He could touch his nose with his tongue, and on the soles of his feet were wheel-shaped marks [physical qualities also attributed to the Buddha]. During the period [of 713-41] he studied the dhyana . . . under Master Huai-jang, who then had nine disciples. Of these only [Ma-tsu] received the sacred mind seal.7 _ However, his real immortality derives from his contribution to the arsenal of methods for shocking novices into enlightenment. It will be recalled that the legendary Sixth Patriarch, Hui-neng, neglected to explain exactly what a person should do to "see into one's own nature." Ma-tsu apparently was the first master who developed non-meditative tricks for nudging a disciple into the state of "no-thought." He was an experimenter, and he pioneered a number of methods that later were perfected by his followers and the descendants of his followers. He was the first master to ask a novice an unanswerable question, and then while the person struggled for an answer, to shout in his ear (he liked the syllable "Ho!")--hoping to jolt the pupil into a non-dualistic mind state. Another similar technique was to call out someone's name just as the person was leaving the room, a surprise that seemed to bring the person up short and cause him to suddenly experience his original nature. A similar device was to deliver the student a sharp blow as he pondered a point, using violence to focus his attention completely on reality and abort ratiocination. Other tricks included responding to a question with a seemingly irrelevant answer, causing the student to sense the irrelevancy of his question. He would also sometimes send a pupil on a "goose chase" between himself and some other enlightened individual at the monastery, perhaps in the hope that bouncing the novice from one personality to another would somehow shake his complacency. Whatever the technique, his goal was always to force a novice to uncover his original nature for himself. He did this by never giving a straight answer or a predictable response and therefore never allowing a disciple to lapse into a passive mental mode.
