Nine Years Facing the Wall
Legend says Bodhidharma sat facing the wall of a cave behind the Shaolin Temple on Mount Song for nine years without a word, until his shadow was said to have printed onto the stone. This near-extreme feat of meditation is the direct source of the later term "facing the wall," and set the Chan style of practice — "pointing directly at the mind," free of elaborate scripture.
The Dialogue With Emperor Wu of Liang That Did Not Accord
Legend says that when Bodhidharma first came to China, Emperor Wu of Liang, a devout Buddhist, asked him, "since taking the throne I have built temples, copied scriptures, and ordained countless monks; what merit is there in this?" Bodhidharma answered, "no merit at all." The emperor asked, "why no merit?" and Bodhidharma said these were but small worldly fruits, "like a shadow following a form, real in seeming but not in truth." The two did not accord, and Bodhidharma crossed the river north — a dialogue often used in Chan to illustrate the basic difference between "seeking blessing through appearances" and "seeing one’s nature."
