Parīkṣit Mahārāja has approached the right person, Śukadeva Gosvāmī. Why? Because he is the disciple and son of Vyāsadeva. So this is paramparā. One should learn from the right person. That is perfect knowledge. We are sticking to Kṛṣṇa consciousness movement because to receive perfect knowledge. If we change, if we become so rascal that "What is spoken in the Vedic literature, there is beyond, something," then we are rascal. There is no beyond. This is perfect knowledge.
So how to take perfect knowledge? Tad viddhi. First of all you try to learn. Tad viddhi. How to learn? Where to learn? Praṇipātena, fully surrendered. If you find somebody that he is somebody important where you can surrender fully, from him. Tad viddhi praṇipāta . . . this is. Our process of Vedic knowledge is how to surrender, not that I hear and I reject it. That is not the way. That is another rascaldom. First of all find out the person where you can surrender.
Surrender means you first of all be convinced that "Here is a person who can give me actual knowledge." Therefore before selecting guru one has to convince himself that "The person whom I am going to accept as guru, whether he actually can give me the knowledge?" That is wanted. Therefore before making guru, the system is, for one year the prospective disciple should hear from the person and then decide. And similarly, the guru also see a person who is actually submissive or not. That is Vaiṣṇava injunction, Hari-bhakti-vilāsa, not that to make a guru as a fashion.
