Thereafter Lord Brahma went with mother earth, Lord Shiva, and all the other demigods to the shore of the ocean of milk. There the demigods worshiped Lord Vishnu, the master of the universe, the supreme God of all gods, who provides for everyone and diminishes everyone's suffering. With great attention they worshiped Him by reciting the Vedic mantras known as the Purusa-sukta. 

While in trance, Lord Brahma heard the words of Lord Vishnu vibrating in the sky. Thus he told the demigods, "O demigods, hear from me the order of Ksirodakasayi Vishnu, the Supreme Person, and execute it attentively without delay. 

Before we submitted our petition to the Lord, He was already aware of the earth's distress and planned to descend. For as long as the Lord moves on earth to diminish its burden by His potency in the form of time, all you demigods should appear through plenary portions as sons and grandsons in the family of the Yadus. 

All your wives should also descend to satisfy Sri Krishna, who will appear as the son of Vasudeva. "The first expansion of Krishna is Sankarsana, who is known as Ananta. He is the origin of all incarnations within this material world. Before the appearance of Lord Krishna, this original Sankarsana will appear as Baladeva just to please Lord Krishna by assisting Him in His transcendental pastimes."
