Vishnupurana 4.2.p5

4.2.p5

There took place a dreadful conflict in the Treta yuga between the gods and demons in which the former were defeated. They accordingly repaired to Vishnu for help and propitiated him by their adorations. Being propitiated the primeval deity, the eternal ruler of the universe, Nārāyana said to them—"What you have desired is known to me. Hear how your desires shall be fulfilled. There is a foremost Kshatriya king named Puranjaya, son of the royal saint Sasāda. Infusing a portion of myself into his body I shall descend on earth and slay all the demons. Do you so endeavour that Putanjaya might engage in the work of the destruction of Asuras". Hearing those words the celestials bowed unto the glorious Vishnu and went to Paranjaya and addressed him, saying, "O foremost of Kshatriyas, we have come to thee to secure thy help in the destruction of our enemies in which we have been engaged. It will not behove thee to neglect our friendship who have come here". Being thus addressed Puranjaya said—"If Indra, the lord of the three worlds, the king of you all, who is known as the performer of hundred sacrifices, agrees to carry me upon his shoulders, I shall then fight with your enemies and help you". The celestials and Indra immediately said "so be it".
