Once the world was overburdened by the unnecessary defense force of different kings, who were actually demons but were posing themselves as the royal order. At that time, the whole world became perturbed, and the predominating deity of this earth, known as Bhūmi, went to see Lord Brahmā to tell of her calamities due to the demoniac kings. Bhūmi assumed the shape of a cow and presented herself before Lord Brahmā with tears in her eyes. She was bereaved and was weeping just to invoke the lord’s compassion. She related the calamitous position of the earth, and after hearing this, Lord Brahmā became much aggrieved, and he at once started for the ocean of milk, where Lord Viṣṇu resides. Lord Brahmā was accompanied by all the demigods, headed by Lord Śiva, and Bhūmi also followed. Arriving on the shore of the milk ocean, Lord Brahmā began to pacify Lord Viṣṇu, who had formerly saved the earthly planet by assuming the transcendental form of a boar.
In the Vedic mantras, there is a particular type of prayer called Puruṣa-sūkta. Generally, the demigods offer their obeisances unto Viṣṇu, the Supreme Personality of Godhead, by chanting the Puruṣa-sūkta. It is understood herein that the predominating deity of every planet can see the supreme lord of this universe, Brahmā, whenever there is some disturbance on his planet. And Brahmā can approach the Supreme Lord Viṣṇu, not by seeing Him directly but by standing on the shore of the ocean of milk. There is a planet within this universe called Śvetadvīpa, and on that planet there is an ocean of milk. It is understood from various Vedic scriptures that just as there is the ocean of salt water on this planet, there are various kinds of oceans on other planets. Somewhere there is an ocean of milk, somewhere there is an ocean of oil, and somewhere there are oceans of liquor and of many other types of liquids. The Puruṣa-sūkta is the standard prayer which the demigods recite to appease the Supreme Personality of Godhead, Kṣīrodakaśāyī Viṣṇu. Because He is lying on the ocean of milk, He is called Kṣīrodakaśāyī Viṣṇu. He is the form of the Supreme Personality of Godhead through whom all the incarnations within this universe appear.
After all the demigods offered the Puruṣa-sūkta prayer to the Supreme Personality of Godhead, they apparently heard no response. Then Lord Brahmā personally sat in meditation, and there was a message-transmission from Lord Viṣṇu to Brahmā. Brahmā then broadcast the message to the demigods. That is the system of receiving Vedic knowledge. The Vedic knowledge is received first by Brahmā from the Supreme Personality of Godhead, through the medium of the heart. As stated in the beginning of Śrīmad-Bhāgavatam, tene brahma hṛdā ya ādi-kavaye: [SB 1.1.1] the transcendental knowledge of the Vedas was transmitted to Lord Brahmā through the heart. Here also, in the same way, only Brahmā could understand the message transmitted by Lord Viṣṇu, and he broadcast it to the demigods for their immediate action. The message was this: The Supreme Personality of Godhead would appear on the earth very soon, along with His supreme powerful potencies, and as long as He remained on the earth planet to execute His mission of annihilating the demons and establishing the devotees, the demigods should also remain there to assist Him. They should all immediately take birth in the family of the Yadu dynasty, wherein the Lord would also appear in due course of time. The Supreme Personality of Godhead Himself, Kṛṣṇa, would personally appear as the son of Vasudeva. Before His appearance, all the demigods, along with their wives, should appear in different pious families in the world just to assist the Lord in executing His mission. The exact word used here is tat-priyārtham, which means the demigods should appear on the earth in order to please the Lord. In other words, any living entity who lives only to satisfy the Lord is a demigod. The demigods were further informed that Ananta, the plenary portion of Lord Kṛṣṇa who is maintaining the universal planets by extending His millions of hoods, would also appear on earth before Lord Kṛṣṇa’s appearance. They were also informed that the external potency of Viṣṇu (Māyā), with whom all the conditioned souls are enamored, would also appear by the order of the Supreme Lord, just to execute His purpose.
After instructing and pacifying all the demigods, as well as Bhūmi, with sweet words, Lord Brahmā, the father of all prajāpatis, or progenitors of the universal population, departed for his own abode, the highest material planet, called Brahmaloka.
