Yampolsky characterizes "no-thought" as follows: "Thoughts are conceived as advancing in progression from past to present to future, in an unending chain of successive thoughts. Attachment to one instant of thought leads to attachment to a succession of thoughts, and thus to bondage. By cutting off attachment to one instant of thought, one may, by a process unexplained, cut off attachment to a succession of thoughts and thus attain to no-thought, which is the state of enlightenment."15 Precisely how this condition of "no-thought" enlightenment is achieved is not explained in the Platform Sutra and in fact has been the major concern of Zen ever since. The one thing that all will agree is that the harder one tries to attain it, the more difficult it becomes. It is there inside, waiting to be released, but it can be reached only through the intuitive mind. And it happens suddenly, when we least expect. The master Hui-neng stands at the watershed of Zen history. Indeed he may be the watershed, in the embodied form of a legend. There seems reason to suspect that he was canonized well after the fact, as was Bodhidharma. But whereas Bodhidharma provided an anchor for the original formation of a separate _Dhyana_ sect in Chinese Buddhism, Hui-neng became the rallying symbol for a new type of Ch'an, one wholly Chinese, and one that seemed to discount Bodhidharma's old mainstay, meditation. He became the Chinese answer to the Indian Bodhidharma. Hui-neng redefined the specific characteristics of the Ch'an goal and described in nontheological terms the mind state in which duality is banished. But he failed to go the next step and explain how to get there. All he did was point out (to use the terminology of logic) that meditation not only was not a sufficient condition for enlightenment, it might not even be a necessary condition. What then was required? The answer to this question was to be worked out during the next phase of Ch'an, the so-called Golden Age of Zen, when a new school of Southern Ch'an exploded (to use a common description) in the south and went on to take over all of Ch'an. These new teachers seem to have accepted Hui-neng as their patron, although the direct connection is not entirely clear. These masters learned how to impose a torture chamber on the logical mind, bringing to it such humiliations that it finally annihilated ego or self and surrendered to _prajna_, intuitive wisdom. They devised systematic ways to produce the state of "no-thought" that Hui-neng and Shen-hui apparently could only invoke. PART II THE GOLDEN AGE OF ZEN
