法苑珠林 12.86

12.86

In the fifty-third year of King Mu of Zhou, at dawn on the fifteenth day of the second month in the year *renshen*, a violent wind suddenly arose, damaging houses, breaking trees, shaking the earth, and clouding the sky. In the west, twelve white rainbows appeared. The Grand Astrologer Hu Duo said, "The sage of the west has passed away." This was precisely the sign of the Buddha's entering nirvāṇa.
