English man: If the spiritual master, Prabhupāda, worships God through a demigod, is he bona fide?
Prabhupāda: No. He does not know how to worship. How he can be bona fide? Kṛṣṇa says, sarva-dharmān parityajya mām ekam (BG 18.66). Why he should go to the demigods? That means he has no knowledge. Kṛṣṇa says, mām ekam. Why should you go to others? That means he's insufficiently qualified. Why should you go to the demigods? What is the necessity? He's not bona fide. Because he has insufficient knowledge. Bona fide spiritual must be sufficiently knowledge. Kṛṣṇa says, mām ekam; God says, mām ekam. Why he should go to demigods? That is his proof that he's not bona fide.
