Wu-Ti's conversion is connected with a wandering monk and magician called Pao-Chih[630], who received the privilege of approaching him at all hours. A monastery was erected in Nanking at great expense and edicts were issued forbidding not only the sacrifice of animals but even the representation of living things in embroidery, on the ground that people might cut up such figures and thus become callous to the sanctity of life. The emperor expounded sûtras in public and wrote a work on Buddhist ritual[631]. The first Chinese edition of the Tripitaka, in manuscript and not printed, was collected in 518. Although Wu-Ti's edicts, particularly that against animal sacrifices, gave great dissatisfaction, yet the Buddhist movement seems to have been popular and not merely an imperial whim, for many distinguished persons, for instance the authors Liu Hsieh and Yao Ch'a[632], took part in it. In 520 (or according to others, in 525) Bodhidharma (generally called Ta-mo in Chinese) landed in Canton from India. He is described as the son of a king of a country called Hsiang-chih in southern India, and the twenty-eighth Patriarch[633]. He taught that merit does not lie in good works and that knowledge is not gained by reading the scriptures. The one essential is insight, which comes as illumination after meditation. Though this doctrine had subsequently much success in the Far East, it was not at first appreciated and Bodhidharma's introduction to the devout but literary Emperor in Nanking was a fiasco. He offended his Majesty by curtly saying that he had acquired no merit by causing temples to be built and books to be transcribed. Then, in answer to the question, what is the most important of the holy doctrines, he replied "where all is emptiness, nothing can be called holy." "Who," asked the astonished Emperor, "is he who thus replies to me?" "I do not know," said Bodhidharma. Not being able to come to any understanding with Wu-Ti, Bodhidharma went northwards, and is said to have crossed the Yang-tse standing on a reed, a subject frequently represented in Chinese art[634]. He retired to Lo-yang where he spent nine years in the Shao-Lin[635] temple gazing silently at a wall, whence he was popularly known as the wall-gazer. One legend says that he sat so long in contemplation that his legs fell off, and a kind of legless doll which is a favourite plaything in Japan is still called by his name. But according to another tale he preserved his legs. He wished to return to India but died in China. When Sung Yün, the traveller mentioned above, was returning from India, he met him in a mountain pass bare-footed and carrying one sandal in his hand[636]. When this was reported, his coffin was opened and was found to contain nothing but the other sandal which was long preserved as a precious relic in the Shao-Lin temple.
