One of Yun-men's sermons reveals much about the growing pains of Ch'an. The seriousness of the novices seems to have been steadily deteriorating, and his characterization of the run-of-the- mill novices of his time presents a picture of waning dynamism. Success was clearly bringing a more frivolous student to the monasteries, and we sense here the warning of a man who rightly feared for the future quality of Ch'an. _Furthermore, some monks, idle and not serious in their studies, gather together trying to learn the sayings of the ancients, and attempt to reveal their own nature through memorizing, imagining, prophesying. These people often claim that they understand what Dharma is. What they actually do is simply talk themselves into endless entanglements and use meditation to pass the time.16 _ He also felt the traditional pilgrimages from master to master had become hardly more than a glorified version of sightseeing. _Do not waste your time wandering thousands of [miles], through this town and that, with your staff on your shoulder, wintering in one place and spending the summer in another. Do not seek out beautiful mountains and rivers to contemplate. . . . [T]he fundamental thing for you to do is to obtain the essence of Ch'an. Then your travels will not have been in vain. If you find a way to guide your understanding under a severe master . . . wake up, hang up your bowl-bag, and break your staff. Spend ten or twenty years of study under him until you are thoroughly enlightened.17 _ He also advised that they try to simplify their search, that they try to realize how uncomplicated Ch'an really is. _Let me tell you that anything you can directly point at will not lead you to the right trail. . . . Besides dressing, eating, moving bowels, releasing water, what else is there to do?18 _ Yun-men was one of the most dynamic masters of the late ninth and early tenth century, providing new twists to the historic problem of nonlanguage transmission. His celebrated solution was the so-called one-word answer. Several of these are preserved in the two major koan collections of later years. Two of the better-known follow: _A monk asked Yun-men, "What is the teaching that transcends the Buddha and patriarchs?" Yun-men said, "A sesame bun._"19_ A monk asked Yun-men, "What is Buddha?" Yun-men replied, "A dried piece of shit._"20_ _ The "one-word" was his version of the blow and the shout. R. H. Blyth is particularly fond of Yun-men and suggests he may have had the keenest intellect of any Ch'an master--and even goes so far as to declare him the greatest man China has produced.21
