In the next Manwantara Vishnu was born of Vikunthi, as Vaikuntha along with the celestials called Vaikunthas. In the present period Vishnu was again born as Vamana the son of Kasyapa by Aditi. With three paces he conquered the worlds and having released them from all disturbances he gave them to Purandara. By these seven persons, in the various Manwantaras, the created beings have been preserved.

In plain words: In a later age, Vishnu was born as Vaikuntha to Vikunthi. In the present age he was born as Vamana, the dwarf son of Kashyapa and Aditi. With three giant steps he won back the worlds and gave them to Indra (Purandara). In each age a form of Vishnu protects all beings.
