So Vedānta-sūtra says, answer, the first aphorism is: athāto brahma jijñāsā. Brahman, the Absolute, that is the main business of the human life, to inquire about the Absolute Truth. Here everything is relative truth. I am the son of my father. My father is the son of his father. His father is the son of his father. You go on. Everything is relative. But who is the Absolute? Who is the Absolute? That inquiry is called Brahma-jijñāsā. Who is the original father? Then if you go on searching like that, within this universe you'll find Lord Brahmā is the origin. He's called, therefore, pitāmaha, Lord Brahmā. But if you still inquire further, who is the father of Brahmā, then you come to Garbhodakaśāyī Viṣṇu. From the Garbhodakaśāyī Viṣṇu, from His abdomen, there sprouted a lotus flower, and (on) the lotus flower, Brahmā was born. Therefore Brahmā's another name is Svayambhūr. He did not come out through the womb of his mother, although the mother was present.
