Ma-tsu also seems to have simplified the idea of what constitutes enlightenment. As he defined it, "seeing into one's own nature" simply meant understanding (intuitively, not rationally) who you are and what you are. This truth could be taught with whatever method seemed appropriate at a given moment. As Hu Shih so eloquently describes his teaching, _ ". . . any gesture or motion, or even silence, might be used to communicate a truth. [Recall the Buddha once enlightened a follower by holding up a flower.] Ma-tsu developed this idea into a pedagogical method for the new Zen. There is no need to seek any special faculty in the mind for the enlightenment. Every behavior is the mind, the manifestation of the Buddha-nature. Snapping a finger, frowning or stretching the brow, coughing, smiling, anger, sorrow, or desire . . . is the functioning of the Buddhahead: it is the Tao, the Way. There is no need to perform any special act, be it dhyana_ _or worship, in order to achieve the Tao. To be natural is the Way. Walk naturally, sit naturally, sleep naturally, live naturally--that is the Way. Let the mind be free: do not purposely do evil; nor purposely do good. There is no Law to abide, no Buddhahood to attain. Maintain a free mind and cling to nothing: that is Tao._"8_ _ Thus it seems that the most preeminent Ch'an master of the eighth century not only repudiated all the apparatus of traditional Buddhism, he also simplified enlightenment down to a quite secular condition of acceptance of the natural state of human affairs. For instance, although he was familiar with the great Mahayana sutras, Ma-tsu never mentions Hui-neng or the Diamond Sutra. His Ch'an, expressed in simple everyday language, seems merely so many ways of finding out who you are and what you are. Furthermore, there seems to be nothing specifically that you can do to accelerate the occurrence of sudden enlightenment, other than use traditional practices to make your psyche as uncomplicated as possible and then wait for the moment to strike (he, of course, experimented to find ways to accelerate the arrival of that moment). But he has nothing encouraging to say about the effectiveness of meditation as an aid to finding the desired non-rational insight, which he sometimes described using the borrowed term "Tao": _Cultivation is of no use for the attainment of Tao. The only thing that one can do is to be free of defilement. When one's mind is stained with thoughts of life and death, or deliberate action, that is defilement. The grasping of the Truth is the function of everyday-mindedness. Everyday-mindedness is free from intentional action, free from concepts of right and wrong, taking and giving, the finite or the infinite. . . . All our daily activities--walking, standing, sitting, lying down--all response to situations, our dealings with circumstances as they arise: all this is Tao.9
