_In the first category, according to Chang Chung-yuan, the ego meets the universal Self.32 In the second category the universal Self encounters the ego-form self. In the third category, the universal Self of one meets the universal Self of another, and in the fourth category the ego of one encounters the ego of another. Or if we are to interpret this in the concrete, in the first encounter, an enlightened master meets an unenlightened novice; in the second an enlightened novice meets an unenlightened master (which did happen); in the third an enlightened master meets an enlightened novice; and in the fourth category an unenlightened master meets an unenlightened novice, to the mutual delusion of both.33 Lin-chi has been called the most powerful master in the entire history of Ch'an, and not without reason. His mind was capable of operating at several levels simultaneously, enabling him to overlay very practical instruction with a comprehensive dialectic. He believed in complete spontaneity, total freedom of thought and deed, and a teaching approach that has been called the "lightning" method--because it was swift and unpredictable. He was uncompromising in his approach, and he was also extremely critical of the state of Ch'an in his time--a criticism probably justified. He found both monks and masters wanting. It seems that Ch' an had become fashionable, with the result that there were many masters who were more followers of the trend than followers of the Way. So whereas Huang-po often railed against other sects of Buddhism, Lin-chi reserved his ire for other followers of Ch'an (there being few other Buddhist sects left to criticize). He even denounced his own students, who often mimicked his shouting without perceiving his discernment in its use. He finally had to set standards for this, announcing to the assembly one day that henceforth only those who could tell the enlightened from the unenlightened would have the right to shout. _ "You all imitate my shouting," he said, "but let me give you a test now. One person comes out from the eastern hall. Another person comes out from the western hall. At their meeting, they simultaneously shout. Do you possess enough discernment to distinguish the guest from the host [i.e., the unenlightened from the enlightened]? If you have no such discernment, you are forbidden hereafter to imitate my shouting.34 _ His major concern seems to have been that his students resist intellection. Lin-chi himself was able to speculate philosophically while still a natural man, using conceptual thought only when it served his purpose. But perhaps his students could not, for he constantly had to remind them that striving and learning were counterproductive.
