襄州峴山華嚴寺盧舍那瑞像者。本是周朝古像。法滅藏之得存。每有凶相以涕出為期。隋文將崩。一鼻涕出。沾污于懷金薄剝起。雖後修飾望還如涕。貞觀末年四月內連涕不止。塗污胸懷方可尺許。

Regarding the miraculous Rocana image of Huayan Temple on Mount Xian in Xiangzhou: it was originally an ancient image from the Northern Zhou dynasty; when the Dharma was abolished, it was hidden away and thus preserved. Whenever an ominous sign was portended, it was marked by the flowing of nasal mucus. When Emperor Wen of the Sui was about to die, mucus flowed from one nostril, soiling its breast, and the gold leaf peeled off. Although it was repaired afterward, looking at it from afar, it still appeared like mucus. In the fourth month of the late Zhenguan reign era, mucus flowed continuously without stopping, soiling the chest and breast over an area about a foot square.
