4.13.53

tacchrutvā vacanaṃ kāvyo jagāma tvaritastataḥ |
apaśyaddānavānāṃ ca pārśve vācaspatiṃ tadā ||

Hearing these words, S’ukrâchârya went hurriedly to the Demons and saw the Devaguru Brihaspatî sitting before them in the guise of S’ukrâchârya. He was explaining to them the Jaina doctrines, compiled by himself and finding fault with the act of envy, taking revenge and killing and cursing the sacrifices, etc.
