Wu-Ti adopted many of the habits of a bonze. He was a strict vegetarian, expounded the scriptures in public and wrote a work on ritual. He thrice retired into a monastery and wore the dress of a Bhikkhu. These retirements were apparently of short duration and his ministers twice redeemed him by heavy payments. In 538 a hair of the Buddha was sent by the king of Fu-nan and received with great ceremony. In the next year a mission was despatched to Magadha to obtain Sanskrit texts. It returned in 546 with a large collection of manuscripts and accompanied by the learned Paramârtha who spent twenty years in translating them[637]. Wu-Ti, in his old age, became stricter. All luxury was suppressed at Court, but he himself always wore full dress and showed the utmost politeness, even to the lowest officials. He was so reluctant to inflict the punishment of death that crime increased. In 547 he became a monk for the third time and immediately afterwards the events connected with Hou-Ching (briefly sketched above) began to trouble the peace of his old age. During the siege of Nanking he was obliged to depart from his vegetarian diet and eat eggs. When he was told that his capital was taken he merely said, "I obtained the kingdom through my own efforts and through me it has been lost. So I need not complain." Hou-Ching proceeded to the palace, but[638], overcome with awe, knelt down before Wu-Ti who merely said, "I am afraid you must be fatigued by the trouble it has cost you to destroy my kingdom." Hou-Ching was ashamed and told his officers that he had never felt such fear before and would never dare to see Wu-Ti again. Nevertheless, the aged Emperor was treated with indignity and soon died of starvation. His end, though melancholy, was peaceful compared with that in store for Hou-Ching who, after two years of fighting and murdering, assumed the imperial title, but immediately afterwards was defeated and slain. The people ate his body in the streets of Nanking and his own wife is said to have swallowed mouthfuls of his flesh. One of Wu-Ti's sons, Yüan-Ti, who reigned from 552 to 555, inherited his father's temper and fate with this difference that he was a Taoist, not a Buddhist. He frequently resided in the temples of that religion, studied its scriptures and expounded them to his people. A great scholar, he had accumulated 140,000 volumes, but when it was announced to him in his library that the troops of Wei were marching on his capital, he yielded without resistance and burnt his books, saying that they had proved of no use in this extremity.
