沙門竺道猷。即帛道猷也。初止剡之石城山。是年又移台州。始豐赤城山（今台州天台山）坐禪石室。有群虎蹲於前。猷誦經。一虎獨睡。猷以如意扣其頭。云何不聽經。輕畢虎皆去。尋有大蛇十圍。竟來環遶舉頭向猷。半日而去。一日有男子來前曰。弟子夏帝之子。居此二千餘年。今往寒石山。輒推室以相奉。遂鳴鞞改角凌雲而去。猷於東晉武帝太元八年入寂（本傳）。

The śramaṇa Zhu Daoyou, that is, Bo Daoyou. Originally he stayed at Mount Shicheng in Shan; in this year he moved to Mount Chicheng in Shifeng of Tai Prefecture (now Mount Tiantai in Tai Prefecture), where he sat in meditation in a stone chamber. A pack of tigers squatted before him; while You chanted scriptures, one tiger alone fell asleep. You tapped its head with a ruyi scepter, saying, 'Why do you not listen to the sūtra?' When the chanting ended, the tigers all departed. Shortly thereafter, a great serpent of ten arm-spans came, coiled around, and held its head high toward You; after half a day, it departed. One day, a man came before him and said: 'Your disciple is a son of an emperor of the Xia; I have dwelt here for more than two thousand years. Now I am going to Mount Hanshi, and I readily yield this chamber to offer it to you.' Thereupon, sounding drums and bugles, he soared into the clouds and departed. You entered quiescence in the eighth year of the Taiyuan era under Emperor Wu of Eastern Jin (His Biography).
