高僧傳 7.5

7.5

初投吳之虎丘山，旬日之中，學徒數百。其年夏，雷震青園佛殿，龍昇于天，光影西壁，因改寺名號曰「龍光」。時人歎曰：「龍既已去，生必行矣。」俄而投迹廬山，銷影巖岫，山中僧眾咸共敬服。後《涅槃》大本至于南京，果稱闡提悉有佛性，與前所說合若符契。

At first, he went to Mount Huqiu in Wu; within ten days, his students numbered several hundred. In the summer of that year, thunder struck the Buddha Hall of Qingyuan Temple, and a dragon ascended to the sky, casting light and shadows on the western wall; the temple's name was consequently changed to Longguang (Dragon Radiance). People of the time sighed and said: "Since the dragon has already departed, Master Daosheng must certainly leave." Soon after, he repaired to Mount Lu and concealed his presence amid the cliffs and peaks; the monastics in the mountain all revered and submitted to him. Later, when the large version of the Nirvāṇa-sūtra arrived in Nanjing, it indeed stated that all icchantikas possess the Buddha-nature, tallying with what he had previously declared like two halves of a tally.
