廣弘明集 2.37

2.37

又云。佛者昔於西胡得道。在三十二天為延真宮主。勇猛苦教。故其弟子皆髠形染衣。斷絕人道。天上衣服悉然。始光年中初奉其書。獻之世祖。乃令謙之止於張曜辟穀之所供其食物。朝野聞之若存若亡。未全信也。崔浩獨異其言。因師事之。受其法術。上疏贊明其事曰。臣聞聖王受命則有天應。而河洛圖書。寄言於蟲獸之文。未若今日人神接對手筆。粲然辭旨深妙。自古無此。昔漢高英聖。四皓猶或恥之。不為屈節。今清德隱仙。不召自至。斯誠陛下侔蹤軒黃應天之符也。豈可以世俗常談而忽上靈之命。臣竊懼之。世祖欣然（時年九歲）乃使謁者奉玉帛牲牢祭嵩岳。迎致其餘弟子在山中者。於是崇奉天師。立道壇顯揚新法。布告天下道業大行。浩事天師甚謹拜禮。人或譏之。

It also said: "The Buddha formerly attained the Way in the Western Hu lands, and in the thirty-two heavens he is the Master of the Palace of Prolonging Truth. Because of his vigorous and arduous teaching, his disciples all shave their hair and dye their robes, severing human relationships. The clothing in heaven is entirely like this." In the middle of the Shiguang reign era, [Qianzhi] first offered these scriptures and presented them to Emperor Shizu. The emperor then ordered Qianzhi to stay at the place where Zhang Yao had practiced grain avoidance, supplying him with food. When the court and the public heard of it, they treated it vaguely, not fully believing it. Cui Hao alone regarded his words as extraordinary, and thereupon served him as a master, receiving his methods and arts. He submitted a memorial praising and clarifying the matter, saying: "Your servant has heard that when sage kings receive the Mandate, there are heavenly omens. But the charts and writings of the Yellow River and Luo River relied on expressions found in the patterns of insects and beasts; they are not like today, where human and spirit meet face to face, and the handwriting is brilliantly clear, with words and concepts profound and subtle. Since antiquity there has been nothing like this. In the past, though Han Gaozu was heroic and sagely, the Four White-Haired Elders of Mount Shang still felt it shameful and would not humble themselves before him. Now a recluse immortal of pure virtue has arrived without summons. This is truly an omen matching Your Majesty with the tracks of Xuanyuan and the Yellow Emperor in responding to Heaven. How could we overlook the command of the supreme spirit as mere vulgar talk? Your servant privately fears it." Emperor Shizu was delighted (he was then nine years old), and thereupon dispatched an usher carrying jade, silk, and sacrificial animals to offer sacrifice at Mount Song, welcoming the rest of Qianzhi's disciples remaining in the mountains. Thereupon, he revered the Celestial Master, erected Daoist altars to make known the new methods, and proclaimed it throughout the empire, so that the practices of the Way flourished greatly. Cui Hao served the Celestial Master with great reverence, bowing and performing rituals, which some people ridiculed.
