Young man (2): But if the disciple is in ignorance before...
Prabhupāda: Yes.
Young man (2): ...how does he know which master to choose? I mean, because he doesn't have the knowledge...
Prabhupāda: Yes.
Young man (2): ...to make a wise selection.
Prabhupāda: Yes. Yes. So the first thing is that one should be searching after a disciple, er, or searching after a spiritual master. Now, just like you search after some school. You search after some school. So when you are searching after some school, you must have at least some preliminary knowledge what a school means. You cannot search after a school and go to a cloth shop. If you are so ignorant that you do not know what is a school and what is a cloth shop, then it is very difficult for you. You must know, at least, what is a school. So that knowledge is like this: tad-vijñānārthaṁ sa gurum eva abhigacchet, samit-pāṇiḥ śrotriyaṁ brahma-niṣṭham (MU 1.2.12). The spiritual master is required for a person who is inquisitive to have transcendental knowledge.
