Perhaps it was all planned, but when Lin-chi arrived at the second monastery and related his unhappy treatment at the hands of Huang-po the master Ta-yu listened patiently and then declared, "Huang-po treated you with great compassion. He merely wanted to relieve your distress." Upon hearing this Lin-chi suddenly understood that Huang-po was transmitting the wordless insight to him, the understanding that Ch'an lies not in the words produced in the abbot's room but rather in the realization of his intuitive mind. It suddenly was all so obvious that the young monk could not contain his joy and declared, "So Huang-po's Buddhism is actually very simple; there's nothing to it after all!" This struck the master Ta-yu as either impertinent or a significant breakthrough, so he grabbed Lin-chi and yelled, "You scamp! A minute ago you complained that Huang-po's teaching was impossible to understand and now you say there is nothing to it. What is it you just realized? Speak quickly!" (Only in a spontaneous utterance is there real, uncalculated evidence of enlightenment.)
Lin-chi's answer was to pummel Ta-yu in the ribs three times with his fist. The older master then discharged him (or perhaps kicked him out) with the observation, "Your teacher is Huang-po, and therefore you do not concern me." Thus the enlightened young novice trudged back up the mountain to Huang-po's monastery. The master greeted him with the puzzled observation: "Haven't you come back a bit too soon? You only just left." In response Lin-chi bowed and said, "It's because you've been so kind to me that I came back so quickly," and he proceeded to relate the story of his sudden enlightenment. To which Huang-po declared, "What a big mouth that old man has. The next time I see him I'll give him a taste of my staff." To this Lin-chi yelled, "Why wait! I can give it to you now," and proceeded to slap the master's face. The startled Huang-po declared, "This crazy monk is plucking the tiger's whiskers." Whereupon Lin-chi emitted the first of what was to be a lifetime of shouts, affirming his wordless insight. The satisfied Huang-po called an attendant and said, "Take this crazy fellow to the assembly hall."
This is a perfect example of "sudden" enlightenment that took many years to achieve. Lin-chi had been a plodding, earnest young man until the moment of his "sudden" enlightenment, which occurred over a seemingly uncalculated remark by a teacher not even his own master. In fact, all Huang-po had done was to assail him with a staff. But Lin-chi was transformed suddenly from a milksop to the founder of a school, probably the greatest radicalization since the Apostle Paul was struck down on the road to Damascus.3 Still, Lin-chi's "sudden" enlightenment had come about at the end of a highly disciplined period of preparation. As he later described it:
In bygone days I devoted myself to the vinaya and also delved into the sutras and sastras. Later, when I realized that they were medicines for salvation and displays of doctrines in written words, I once and for all threw them away, and searching for the Way, I practiced meditation. Still later I met great teachers. Then it was, with my Dharma Eye becoming clear, that I could discern all the old teachers under Heaven and tell the false ones from the true. It is not that I understood from the moment I was born of my mother, but that, after exhaustive investigation and grinding discipline, in an instant I knew of myself.4
Like a reformed addict, he railed most against his own recent practices. He proceeded to denounce all the trappings of Buddhism, even the Ch'an Patriarchs themselves, as he shattered the chains of his former beliefs:
Followers of the Way, if you want insight into Dharma as is, just don't be taken in by the deluded views of others. Whatever you encounter, either within or without, slay it at once: on meeting a buddha slay the buddha, on meeting a patriarch slay the patriarch, on meeting an arhat slay the arhat, on meeting your parents slay your parents, on meeting your kinsman slay your kinsman, and you attain emancipation. By not cleaving to things, you freely pass through.5
After his enlightenment, he had many exchanges with Huang-po in which he came off ahead as often as not. It is also interesting that many of the interactions involved the manual labor of the monastery, an indication of the significance of work in Ch'an life. One famous joust between Lin-chi and Huang-po went as follows:
One day Master Lin-chi went with Huang-po to do some work in which all the monks participated. Lin-chi followed his master who, turning his head, noticed that Lin-chi was carrying nothing in his hand.
"Where is your hoe?"
"Somebody took it away."
