Guest (1): Are you knowing people take dīkṣā from many gurus?
Prabhupāda: No, dīkṣā-guru is one.
Guest (1): One.
Prabhupāda: But śikṣā-guru can be many.
Guest (1): But suppose dīkṣā-gurus or people take one mantra from one guru and other one . . .
Prabhupāda: Then you have not selected guru; you have selected some rascal. Guru can be . . . cannot be different. Guru means one who knows the science of Kṛṣṇa. Yei kṛṣṇa-tattva-vettā sei guru haya (CC Madhya 8.128). Anyone who knows the science . . . So suppose if you want to become medical man, you must go to a qualified medical man to learn. And if you go to a pān-wālā, what he'll teach you? That is your mistake. Guru cannot be different. Guru is one, one who knows the science of Kṛṣṇa. If he does not know, then he is not guru. Why should you go there?
Guest (1): How should we know that he knows about Kṛṣṇa?
Prabhupāda: That requires your fortune. Little intelligence. Therefore Caitanya Mahāprabhu says, ei rūpe brahmāṇḍa bhramite kona bhāgyavān jīva (CC Madhya 19.151). That intelligence is for the most fortunate person. That is not ordinary thing. But guru means who knows the science of Kṛṣṇa. If you go to a bogus man, that is your misfortune. So this is the description of guru: yei kṛṣṇa-tattva-vettā sei guru haya, Caitanya Mahāprabhu's statement.
- kibā vipra kibā śūdra nyāsī kene naya
- yei kṛṣṇa-tattva-vettā sei guru haya
- (CC Madhya 8.128)
It doesn't matter whether he is a sannyāsī or gṛhastha or a brāhmaṇa or śūdra. It doesn't matter. If he knows the science of Kṛṣṇa, then he remains guru.
