"I am herding an ox," the man replied, a metaphorical way of saying he was trying to discipline himself. "And how," shot back Ma-tsu, "do you go about tending it?" The monk replied, "Whenever it starts to go to grass [i.e., self-indulgence], I yank it back by the nostrils [the tender part of the great animal]." To which Ma-tsu admiringly replied, "If you really can do that by yourself, then I may as well retire."21 This story illustrates the emphasis on self-control that was a part of the Ch'an monasteries. Yet self-control was only to be practiced for what it gave in return. There were no value judgments or rules that had to be followed. The point was to do what seemed the most rewarding. For example, there is a story that a local governor asked Ma-tsu, "Master, should I eat meat and drink wine?" The master did not give him a reply that implied a value judgment, but rather outlined the rewards of the two possible paths: "To eat and drink is your natural right, to abstain from meat and wine is your chance for greater blessedness."22 Ma-tsu often used the structure of language, with its natural capacity for parallels, as a teaching tool in itself. _Another time a monk asked, what is the meaning of Bodhidharma coming from the West?" "What is the meaning [of your asking] at this moment?" replied the Master.23 _ The monk was interested in abstract issues (using the Ch'an metaphor for enlightenment's meaning); Ma-tsu reminded him that the only reality that mattered was his own being, his own needs. And he did it using almost identical language. Ma-tsu was constantly testing his disciples, keeping them on their toes and reinforcing their enlightenment. There is the story that one evening while enjoying the moonlight with three of his disciples (including the two most famous, Huai-hai and Nan- ch'uan), he asked them the question "what should we do right now, this very moment?"--a typical Zen challenge. One of the monks said, "It would be best to be studying the sutras of the ancients who have achieved enlightenment." The monk Huai-hai, who was later to receive Ma-tsu's mantle, countered, "It would be good to practice meditation." At that point Nan-ch'uan, the third monk, simply rose, shook the sleeves of his robe, and silently walked away. Ma-tsu acknowledged this as the right answer and declared, "The sutra scriptures are returnable to the Buddhist canon, and meditation to the undifferentiated ocean, but Nan-ch'uan alone leaps over and transcends these."24 Nan-ch'uan's response was a triumph of physical action and simplicity over religiosity and abstraction.
