We now come to the most characteristic feature of Zen Buddhism, by which it is distinguished not only from all the other Buddhist schools, but from all forms of mysticism that are ever known to us. So far the truth of Zen has been expressed through words, articulate or otherwise, however enigmatic they may superficially appear; but now the masters appeal to a more direct method instead of verbal medium. In fact, the truth of Zen is the truth of life, and life means to live, to move, to act, not merely to reflect. Is it not the most natural thing for Zen, therefore, that its development should be towards acting or rather living its truth instead of demonstrating or illustrating it in words, that is to say, with ideas? In the actual living of life there is no logic, for life is superior to logic. We imagine logic influences life, but in reality man is not a rational creature so much as we make him out, of course he reasons, but he does not act according to the result of his reasoning pure and simple. There is something stronger than ratiocination. We may call it impulse, or instinct, or, more comprehensively, will. Where this will acts there is Zen, but if I am asked whether Zen is a philosophy of will I rather hesitate to give an affirmative answer. Zen is to be explained, if at all explained it should be, rather dynamically than statically. When I raise the hand thus, there is Zen. But when I assert that I have raised the hand, Zen is no more there. Nor is there any Zen when I assume the existence of somewhat that may be named will or anything else. Not that the assertion or assumption is wrong, but that the thing known as Zen is three thousand miles away as they say. An assertion is Zen only when it is in itself an act and does not refer to anything that is asserted in it. In the finger pointed at the moon there is no Zen, but when the pointing finger itself is considered, altogether independent of any external references, there is Zen.
