Hence the concluding chapter on “The Ten Cow-herding Pictures.” There are many more topics with which one ought to be acquainted in the study of Zen Buddhism, and some of them, considered by the author the more important, will be treated in the second series of the Essays. ZEN AS CHINESE INTERPRETATION OF THE DOCTRINE OF ENLIGHTENMENT ZEN AS CHINESE INTERPRETATION OF THE DOCTRINE OF ENLIGHTENMENT _Foreword_ Before I proceed to the discussion of the main idea of this essay, which is to consider Zen the Chinese way of applying the doctrine of Enlightenment in our practical life, I wish to make some preliminary remarks concerning the attitude of some Zen critics and thereby to define the position of Zen in the general body of Buddhism. According to them, Zen Buddhism is not Buddhism, it is something foreign to the spirit of Buddhism, and that it is one of those aberrations which we often see growing up in the history of any religion. Zen is thus, they think, an abnormality prevailing among the people whose thought and feeling flow along a channel different from the main current of Buddhist thought. Whether this allegation is true or not, will be decided, on the one hand, when we understand what is really the essence or genuine spirit of Buddhism, and, on the other, when we know the exact status of Zen doctrine in regard to the ruling ideas of Buddhism as they are accepted in the Far East. It may also be desirable to know something about the development of religious experience in general. When we are not prepared thoroughly to understand these questions in the light of the history and philosophy of religion, we may come dogmatically to assert that Zen is not Buddhism just because it looks so different on its surface from what some people with a certain set of preconceived notions consider Buddhism to be. The statement of my position as regards these points will therefore pave the way to the development of the principal thesis.
