The idea of absolute oneness is not the exclusive possession of Zen, there are other religions and philosophies that preach the same doctrine. If Zen, like other monisms or theisms, merely laid down this principle and did not have anything specifically to be known as Zen, it would have long ceased to exist as such. But there is in Zen something unique which makes up its life and justifies its claim to be the most precious heritage of Eastern culture. The following “mondo” or dialogue (literally, questioning and answering)[6.1] will give us a glimpse into the ways of Zen. A monk asked Jōshu (Chao-chou), one of the greatest masters in China,[6.2] “What is the one ultimate word of truth?” Instead of giving him any specific answer, he made a simple response saying, “Yes.” The monk who naturally failed to see any sense in this kind of response asked for a second time, and to this the master roared back, “I am not deaf!”[f125] See how irrelevantly (shall I say?) the all-important problem of absolute oneness or of the ultimate reason is treated here! But this is characteristic of Zen, this is where Zen transcends logic and overrides the tyranny and misrepresentation of ideas. As I said before, Zen mistrusts the intellect, does not rely upon traditional and dualistic methods of reasoning, and handles problems after its own original manners. To cite another instance before going further into the subject proper. The same old Jōshu was asked another time, “One light divides itself into hundreds of thousands of lights; may I ask where this one light originates?”[f126][6.5] This question like the last mentioned is one of the deepest and most baffling problems of philosophy. But the old master did not waste much time in answering the question, nor did he resort to any wordy discussion. He simply threw off one of his shoes without a remark. What did he mean by it? To understand all this, it is necessary that we should acquire a “third eye” as they say, and learn to look at things from a new point of view.
