Veda, your question, Veda knowledge means from the beginning of the creation. Unless this knowledge is there, how this creation can be conducted? So Brahmā was made in charge of this universe, and he was educated in Vedas. Therefore you'll find the Brahmā's picture, he has got Vedas in his hand. Have you seen? Brahmā's picture, he has got Vedas. And in the Śrīmad-Bhāgavatam it is said, tene brahma hṛdā ādi-kavaye . . . ādi-kavaye means he is the original learned man. And the disciplic succession comes from Brahmā.
Brahmā was educated by Kṛṣṇa, and from Brahmā, his disciple Nārada, and Nārada's disciple Vyāsa, Vyāsa's disciple Madhvācārya. In the Madhvācārya, Lord Caitanya in the line. From Lord Caitanya, others. In this way the disciplic succession is coming directly from Kṛṣṇa. And it is called Brahma-sampradāya. Brahma-sampradāya.
So that knowledge . . . evaṁ paramparā-prāptam (BG 4.2). As it is stated in the Bhagavad-gītā, this knowledge is received by this disciplic succession. That is perfect knowledge. No adulteration. Just like if you see water directly from the sky, it is pure water. And as soon as you take water either from sea or river, it is adulterated. Similarly, we have to receive knowledge direct from Kṛṣṇa. So it is a great opportunity that Bhagavad-gītā is directly imparted by Kṛṣṇa. And if we take, accept Bhagavad-gītā as it is, we are full of knowledge.
