_One day when Yuan-wu had taken the high seat in the lecture hall, he said: "A monk asked Yun-men: 'From whence come all the buddhas?' Yun- men answered: 'The East Mountain walks over the water.' But if I were asked, I would not answer that way. 'From whence come all the buddhas?' A fragrant breeze comes of itself from the south, and in the palace pavilion a refreshing coolness stirs." At these words [Ta-hui] suddenly attained enlightenment.13 _ After this he grew in experience and wisdom, eventually taking over many temple duties from Yuan-wu. He soon became a part of the Ch'an establishment in the north and in 1126 was even presented with an official robe and title from a minister. Then suddenly, in the midst of this tranquillity, outside forces intervened to change dramatically the course of Chinese history. For many years previous, China had been threatened by nomadic peoples from the north and west, peoples whom the Chinese haughtily identified as "barbarians." The Sung emperors, cloistered gentlemen in the worst sense of the term, had maintained peace in their slowly shrinking domain by buying off belligerent neighbors and occasionally even ceding border territories. They thought their troubles finally might be easing somewhat when their hostile neighbors were overwhelmed by a new warring tribe from Manchuria. But after a series of humiliating incidents, the Chinese found themselves with merely a new enemy, this time more powerful than any before. China was at last on the verge of being overwhelmed, something it had forestalled for many centuries. Even the invention of gunpowder, which the Chinese now used to fire rocket- propelled arrows, could not save them. Before long the barbarians marched on the capital, and after some years of Chinese attempts at appeasement, the invaders carried off the emperor and his entire court to Manchuria. The year was 1127, which marked the end of the Chinese dynasty now known as the Northern Sung (960-1127). After this disheartening setback a son of the former emperor moved south and set up a new capital in the coastal city of Hangchow, whose charms the Chinese were fond of comparing favorably with heaven (in the refrain, "Heaven above; Hangchow below"). This new regime, known as the Southern Sung (1127-1279), witnessed yet another transformation of Ch'an. Among other things, Southern Ch'an came to resemble eighth-century Northern Ch'an, in its close association with the court and the intelligentsia.
