One of his most often repeated exchanges concerned the question of the difference between the "moon" (i.e., enlightenment) and the "finger pointing at the moon," (i.e., the teaching leading to enlightenment). It was a common observation that students confused the finger pointing at the moon with the moon itself, which is to say they confused talk about enlightenment with the state. One day a monk came along who thought he was smart enough to get around the dilemma. _A monk asked, "As for the finger, I will not ask you about it. But what is the moon?" The Master said, "Where is the finger that you do not ask about?" So the monk asked, "As for the moon, I will not ask you about it. But what is the finger?" The Master said, "The moon!" The monk challenged him, "I asked about the finger; why should you answer me, 'the moon'?" The Master replied, "Because you asked about the finger._"25 At age seventy-four Fa-yen died in the manner of other great masters, calmly and seated in the meditation posture. Part of the lineage of Shih-t'ou and an offshoot of the branch of Ch'an that would become Soto, he was a kindly individual with none of the violence and histrionics of the livelier masters. However, his school lasted only briefly before passing into history. Nonetheless, a number of disciples initially perpetuated his memory, and his wisdom is preserved in various Sung-period compilations of Ch'an sermons. Chapter Fourteen TA-HUI: MASTER OF THE KOAN To confront the koan--the most discussed, least understood teaching concept of the East--is to address the very essence of Zen itself. In simple terms the koan is merely a brief story--all the encounters between two monks related here could be koans. During the Sung Dynasty (960-1279) these stories were organized into collections, commented upon, and structured into a system of study--which involved meditating on a koan and arriving at an intuitive "answer" acceptable to a Zen master. Faced with the threatening intellectualism of the Sung scholars, Ch'anists created the koan out of the experience of the older masters, much the way a liferaft might be constructed from the timbers of a storm-torn ship. But before we examine this raft, it would be well to look again at the ship. It will be recalled that Ch'an grew out of both Buddhism and Taoism, extracting from them the belief that a fundamental unifying quality transcends all the diversity of the world, including things that appear to be opposite. However, Ch'an taught that this cannot be understood using intellectualism, which rationally makes distinctions and relates to the world by reducing it to concepts and systems. One reason is that all rationality and concepts are merely part of a larger, encompassing Reality; and trying to reach this Reality intellectually is like trying to describe the outside of a building while trapped inside.
