You may be a very religious person—never mind you are Hindu, Muslim or Christian or anyone—or according to your religious principles, ritualistic ceremonies, you execute very nicely, svanuṣṭhitaḥ puṁsām. But after doing all these things, if you do not become God consciousness, God conscious, or you do not understand what is God, then the Bhāgavata says that it is simply waste of time. Śrama eva hi kevalam.
So human life is meant for understanding the Supreme, our connection with the Supreme Being. That is real human life. Therefore the Vedas are there. So as soon as Brahmā was born . . . Because he is in charge of this universe. There are innumerable universes and innumerable Brahmās also. Yasya prabhā prabhavato jagad-aṇḍa koṭi (BS 5.40). Yasyaika-niśvasita-kālam athāvalambya jīvanti loma-vilajā jagad-aṇḍa-nāthāḥ (BS 5.48). So Brahmā is jagad-aṇḍa-nātha. He's the chief person within this material world, in this universe. So he is in charge; therefore he was given the Vedic knowledge.
