Śrī Śukadeva Gosvāmī continued: The first created being and most powerful demigod in this universe is Lord Brahmā, who is always responsible for developing universal affairs. Born directly from the Supreme Personality of Godhead, he dedicates his activities to the welfare of the entire universe, for he knows the purpose of the universal creation. This supremely powerful Lord Brahmā, accompanied by his associates and the personified Vedas, left his own abode in the highest planetary system and descended to the place of Prince Priyavrata’s meditation.
