28.51

搜神記曰。崑崙之墟有炎火之山。山上有鳥獸草木。皆生於炎火之中。故有火浣布。非此山草木之皮。則獸之毛也。魏文帝以為火性酷烈無含養之氣。著之典論刊廟門之外。是時西域使人獻火浣布袈裟。於是刊滅此論。

The Soushen ji says: In the wastes of Kunlun, there is a mountain of blazing fire. Upon the mountain there are birds, beasts, grasses, and trees, all born within the blazing fire. Therefore, there is fire-cleansed cloth; if it is not the bark of grasses and trees of this mountain, then it is the fur of the beasts. Emperor Wen of Wei considered that the nature of fire is harsh and fierce, possessing no nurturing vapor, and inscribed this in his Dianlun, carving it outside the temple gates. At that time, an envoy from the Western Regions presented a kāṣāya of fire-cleansed cloth; thereupon this treatise was scraped away and erased.
