Just like Kṛṣṇa . . . Kṛṣṇa, the original father, Supreme Personality of Godhead, He spoke the Vedic knowledge to Brahmā, Lord Brahmā. He spoke to Nārada. Nārada spoke to Vyāsa. Vyāsa spoke to Madhvācārya. So in this disciplic succession, Lord Caitanya, from Lord Caitanya, the six Gosvāmīs, and similarly, coming down, down, Bhaktivinoda Ṭhākura, then Gaurakiśora dāsa Bābājī Mahārāja, then my spiritual master, then we are, next generation, my disciples.
So there is a disciplic succession, and the ācāryas, they're authorities. Our process of knowledge is very simple, we take it from the authority. We don't speculate. Speculation will not help us to come to the real knowledge. Just like when we are in difficulty, in legal implication, we go to some authority, lawyer.
When we are diseased we go to a physician, the authority. There is no use, speculation. Suppose I am in difficulty in some legal implication. I simply speculate, "I shall be free in this way and that way." That will not help. We have to go to the lawyer who knows things, and he gives us instruction that "You do like this; then you'll be free."
Similarly, when we are diseased, if I speculate at home that, "My disease will be cured in this way and that way," no. That is useless. You go to an authorized physician, and he will give you a nice prescription, and you'll be cured. That is the process of knowledge.
But in the modern age people think that "I am free, I am independent, and I can make my own solution." That is rascaldom. That's not good. So Arjuna, when he was talking with Kṛṣṇa as friend, but when he saw that there was no solution talking like this, he surrendered to Kṛṣṇa. He said, śiṣyas te 'ham (BG 2.7). Aham: "Myself, I surrender unto You as Your disciple." Śiṣyas te 'haṁ śādhi māṁ prapannam. Prapannam means surrender.
