People are affectionate to father and mother, and they hesitate how to give up . . . Especially boys, give up the company of family, father and mother, take to Kṛṣṇa consciousness. But here in the śāstra it is said, "If the father is demon or a mother is demon or a friend is demon or a family member is demon, they should not be accepted as relative." Pitā na sa syāj jananī na sā syād gurur na sa syāt (SB 5.5.18). Even guru. If you have accepted somebody as guru but he's a demon, he should be rejected immediately. Immediately. Just like in India there is a system of jāta-guru, the guru by caste. By familywise, they become guru. One family is attached to another guru family by hereditary rules, the sons, after sons accepting guru, the other party, and there is regular business. So such kind of guru is not wanted.
Śrī Jīva Gosvāmī has recommended that laukika-guru . . . This is laukika-guru. Parityāgena adhyātmika paramārthika guru accepted. Guru has to be accepted who is actually paramārthika, advanced in spiritual knowledge, not the formality. That is recommended by Jīva Gosvāmī. Parityāgena. Parityāga vidhīyate. Śāstra says, "If the guru does not know the right thing, he can be given up." So what is the right thing? Right thing is to become devotee. First of all the śāstric injunction is that anyone who is not a devotee, he cannot become guru. He cannot become guru. Avaiṣṇava, he cannot become guru. He must be a Vaiṣṇava.
