As soon as Brahma was born of the abdominal lotus petals of Visnu, he was impregnated with Vedic knowledge, and therefore he is known as veda-garbha, or a Vedantist from the embryo. Without Vedic knowledge, or perfect, infallible knowledge, no one can create anything. All scientific knowledge and perfect knowledge are Vedic. One can get all types of information from the Vedas, and as such, Brahma was impregnated with all-perfect knowledge so that it was possible for him to create. Thus Brahma knew the perfect description of creation, as it was exactly apprised to him by the Supreme Lord Hari. Brahma, on being questioned by Narada, told Narada exactly what he had heard directly from the Lord. Narada again told exactly the same thing to Vyasa, and Vyasa also told Sukadeva exactly what he heard from Narada. And Sukadeva was going to repeat the same statements as he had heard them from Vyasa. That is the way of Vedic understanding. The language of the Vedas can be revealed only by the above-mentioned disciplic succession, and not otherwise.
