1.136

又復不久，有天來，云姓姚氏，云：「弟子天人，自有姓字，語同天竺。師既不解，還述本音。」（云云。）

Then shortly afterward, another deva arrived, who said his surname was Yao, and said: "This disciple is a deva, and naturally has his own surname and personal name, with speech identical to India. Since the Master does not understand it, I shall speak again using the original sounds." And so on.
