經律異相 21.15

21.15

如是往反。時大仙人言。橫相嗟嘆言虛無實。蠱狐者調達是。鳥者拘迦利是。仙人者則菩薩是（出佛說蠱狐鳥經）。

Thus they went back and forth. At that time, a great immortal said: "They improperly praise each other; their words are empty and devoid of truth." The jackal was Devadatta, the bird was Kokālika, and the immortal was the Bodhisattva.' (Extracted from the Fo shuo guhu niao jing).
