46.16

元符元年。袁州木平山有舍利石塔自然出現。夜放五色虹光。有丈六佛在月輪中。觀音羅漢列侍左右。

In the first year of Yuanfu, a stone relic stupa appeared spontaneously on Mount Muping in Yuanzhou. At night, it emitted rainbow light of five colors, and a sixteen-foot Buddha appeared in the lunar disc, with Avalokiteśvara and arhats standing in attendance to the left and right.
