In the Bhagavad-gītā you find, teṣāṁ satata-yuktānām: those who are constantly engaged in Kṛṣṇa consciousness. Satata means constantly. Teṣāṁ satata-yuktānām, engaged. How? How engaged? Bhajatāṁ prīti-pūrvakam: rendering service with faith and love. Only those persons. Those persons who are in Kṛṣṇa consciousness, and rendering service with faith and love, to them only.
Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam dadāmi buddhi-yogaṁ taṁ (BG 10.10): "I give them buddhi-yogaṁ the intelligence." What sort of intelligence? Dadāmi buddhi-yogaṁ yena mām upayānti te: "Such intelligence by which, by help of which, he can gradually come to My kingdom." That is there. So from within, there is education, and from without, there is education. So we have to take advantage.
So 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.
There is no question of research or bothering your brain. You take directly, immediately. We receive knowledge in that way, oh . . . just mother gives the child education, "My dear child, here is your father. Here is your brother. Here is your sister," the child accepts it. He doesn't require to make research, "Who is my father?" The mother says, authority, "Here is your father," and accept. Finish.
