In the reign of Wu-Ti, the first Emperor of the Ch'i dynasty, one of the imperial princes, named Tzŭ Liang[626], cultivated the society of eminent monks and enjoyed theological discussions. From the specimens of these arguments which have been preserved we see that the explanation of the inequalities of life as the result of Karma had a great attraction for the popular mind and also that it provoked the hostile criticism of the Confucian literati. The accession of the Liang dynasty and the long reign of its first emperor Wu-Ti (502-549) were important events in the history of Buddhism, for this monarch rivalled Asoka in pious enthusiasm if not in power and prosperity. He obviously set the Church above the state and it was while he was on the throne that Bodhidharma came to China and the first edition of the Tripitaka was prepared. His reign, though primarily of importance for religion, was not wanting in political interest, and witnessed a long conflict with Wei. Wu-Ti was aided by the dissensions which distracted Wei but failed to achieve his object, probably as a result of his religious preoccupations, for he seemed unable to estimate the power of the various adventurers who from time to time rose to pre-eminence in the north and, holding war to be wrong, he was too ready to accept insincere overtures for peace. Wei split into two states, the Eastern and Western, and Hou-Ching[627], a powerful general who was not satisfied with his position in either, offered his services to Wu-Ti, promising to add a large part of Ho-nan to his dominions. He failed in his promise but Wu-Ti, instead of punishing him, first gave him a post as governor and then listened to the proposals made by the ruler of Eastern Wei for his surrender. On this Hou-Ching conspired with an adopted son of Wu-Ti, who had been set aside as heir to the throne and invested Nanking. The city was captured after the horrors of a prolonged siege and Wu-Ti died miserably. Wu-Ti was not originally a Buddhist. In fact until about 510, when he was well over forty, he was conspicuous as a patron of Confucianism. The change might be ascribed to personal reasons, but it is noticeable that the same thing occurred in Wei, where a period of Confucianism was succeeded by a strong wave of Buddhism which evidently swept over all China. Hu[628], the Dowager Empress of Wei, was a fervent devotee, though of indifferent morality in both public and private life since she is said to have poisoned her own son. In 518 she sent Sung Yün and Hui Shêng[629] to Udyâna in search of Buddhist books of which they brought back 175.
