Yê-sei (Hui-ch‘ing), of Basho (Pa-chiao), probably of the tenth century, once made the following declaration: “When you have a staff, I will give you one; when you have none, I will take it away from you.”[1.19] This is one of the most characteristic statements of Zen, but later Bokitsu (Mu-chi), of Daiyi (Ta-wei), was bold enough to challenge this by saying what directly contradicts it, viz., “As to myself, I differ from him. When you have a staff, I will take it away from you; and when you have none, I will give you one. This is my statement. Can you make use of the staff? or can you not? If you can, Tokusan (Tê-shan) will be your vanguard and Rinzai (Lin-chi) your rearguard. But if you cannot, let it be restored to its original master.”[1.20] A monk approached Bokuju and said, “What is the statement surpassing [the wisdom of] all Buddhas and Patriarchs?” The master instantly held forth his staff before the congregation, and said, “I call this a staff, and what do you call it?” The monk who asked the question uttered not a word. The master holding it out again, said, “A statement surpassing [the wisdom of] all Buddhas and Patriarchs,—was that not your question, O monk?”[1.21] To those who carelessly go over such remarks as Bokuju’s may regard them as quite nonsensical. Whether the stick is called a staff or not, it does not seem to matter very much as far as the divine wisdom surpassing the limits of our knowledge is concerned. But the one made by Ummon, another great master of Zen, is perhaps more accessible. He also once lifted his staff before a congregation and remarked: “In the scriptures we read that the ignorant take this for a real thing, the Hinayanists resolve it into a nonentity, the Pratyekabuddhas regard it as a hallucination, while the Bodhisattvas admit its apparent reality, which is, however, essentially empty.” “But,” continued the master, “monks, you simply call it a staff when you see one. Walk or sit as you will, but do not stand irresolute.”[1.22] The same old insignificant staff and yet more mystical statements from Ummon. One day his announcement was: “My staff has turned into a dragon, and it has swallowed up the whole universe; where would the great earth with its mountains and rivers be?”[1.23] On another occasion, Ummon, quoting an ancient Buddhist philosopher who said that “Knock at the emptiness of space and you hear a voice; strike a piece of wood and there is no sound,” Ummon took out his staff, and striking space, he cried, “Oh, how it hurts!” Then tapping at the board, he asked, “Any noise?” A monk responded, “Yes, there is a noise.”[f12][1.24] Thereupon exclaimed the master, “O you ignoramus!”
