4.14.10

evaṃ te niścayaṃ kṛtvā tato bhārgavamabruvan |
ayaṃ gururno dharmātmā buddhidaśca hite rataḥ ||

The Daityas thus convinced said to the real S’ukrâchârya, “this man before us is our Guru for our welfare and enlightenment, he is the foremost religious S’ukrâchârya; for ten years continuously he is giving us advices. You are not our Guru; you appear fictitious and false; you better leave this place and go away.”
