All the monks assumed that the leading scholar of the monastery, Shen- hsiu, would naturally win the contest, and all resolved not to bother composing lines of their own. The story tells that Shen-hsiu struggled for four days and finally mounted his courage to write an unsigned verse on a wall corridor at midnight. _Our body is the Bodhi-tree, And our mind a mirror bright. Carefully we wipe them hour by hour, And let no dust alight.5 _ This verse certainly demonstrated the concept of the mind's nonattachment to phenomena, but perhaps it showed an attachment of the mind to itself. In any case, it did not satisfy the Fifth Patriarch, who recognized its author and advised Shen- hsiu privately to submit another verse in two days. Before he had a chance, however, the illiterate Hui-neng, between sessions of rice pounding, chanced along the hallway and asked that the verse be read to him. Upon hearing it, he dictated a stanza to be written next to it. _There is no Bodhi-tree, Nor stand of a mirror bright. Since all is void, Where can the dust alight_?6 The story says that all were amazed, and the Fifth Patriarch immediately rubbed away the stanza lest the other monks become jealous. He then summoned Hui-neng late at night, expounded the Diamond Sutra to him, and presented him with the robe and begging bowl of Bodhidharma-- together with advice to flee south in the interest of safety. Thus Hui-neng became the Sixth Patriarch, began the Southern school of Ch'an, which would later be transmitted to Japan, and established the Diamond Sutra as the faith's primary scripture. And so it was that the Lankavatara Sutra of Bodhidharma, a rich moral and spiritual treatise, was replaced by the more easily understood Diamond Sutra, a repetitive and self- praising document whose message is that nothing exists: _notions of selfhood, personality, entity, and separate individuality, as really existing, are erroneous--these terms are merely figures of speech. . . . Develop a pure, lucid mind, not depending upon sound, flavor, touch, odor, or any quality . . . develop a mind which alights upon no thing whatsoever.7 _ With this _sutra_ as text, the Southern Ch'an masters turned ever farther away from intellectual inquiry, since even the mind itself does not exist. (It has even been suggested that the biography of the founder of Southern Ch'an was revised in later vears to render him as unschooled and illiterate as possible, the better to emphasize the later Ch'an's contempt for scholars and scholarship.)
