3.33

佛涅槃後。諸國王君王傳。聞佛說金剛座量。遂以兩軀觀自在菩薩像。南北標界。東西而坐。聞諸耆舊曰。此菩薩像身沒不見。佛法當盡。今南隅菩薩沒過臆矣。玄奘法師。大宋皇帝貞觀三年己丑八月。首途西域。周穆王滿五十二年壬申。佛七十九。以二月十五日中夜入滅。至首途年。一千五百七十八年矣。

After the Buddha's nirvāṇa, according to the accounts of the kings of various states, having heard the Buddha explain the dimensions of the vajrāsana, they set up two statues of the Bodhisattva Avalokiteśvara, marking the boundaries to the north and south, facing east and west. It is heard from the elders: 'When the bodies of these bodhisattva statues sink and disappear, the Buddha-Dharma will come to an end.' Now the statue at the southern corner has already sunk past its chest. Dharma Master Xuanzang set out for the Western Regions in the eighth month of the jichou year, the third year of the Zhenguan reign of the great Tang emperor [629 CE]. The Buddha, at the age of seventy-nine, in the renshen year, the fifty-second year of King Mu of Zhou, entered extinction in the middle of the night on the fifteenth day of the second month. Up to the year [Xuanzang] set out, it was 1,578 years.
