高僧傳 11.12

11.12

晉太元中，有妖星，帝普下諸國：有德沙門，令齋懺悔攘災。猷乃祈誠冥感。至六日旦，見青衣小兒來悔過云：「橫勞法師，是夕星退。」別說云：「攘星是帛僧光。」未詳。

During the Taiyuan reign of the Jin, an ominous star appeared. The Emperor issued an edict to all provinces: śramaṇas of virtue were ordered to observe a fast, repent, and avert the disaster. Tanyou then prayed with sincerity, moving the unseen realm. At dawn on the sixth day, he saw a small boy dressed in green come to confess, saying: "We have troubled the Dharma Master in vain; this evening the star will retreat." Another account says: "The one who averted the star was Bo Sengguang." It is not clear which is correct.
