Zen is not, in my view, philosophy or mysticism. It is simply a practice of readjustment of nervous activity. That is, it restores the distorted nervous system to its normal functioning.

You know the Zen question, 'The Bodhisattva of Great Mercy' has a thousand hands and a thousand eyes; 'which is the true eye?' I could not understand this for a long time. But the other day, when I looked at the pine trees bending before the cold blasts from the mountain, I suddenly realized the meaning. You see, all the boughs, branches, twigs, and leaves simultaneously bend to the wind with tremendous vigor.
