The Fifth Manvantara
Skandha VIII. Chap. 5
Raivata was the fifth Manu. He was the brother of Tâmasa. His sons were Arjuna, Bali, Vindhya and others. Vibhu was Indra. Bhûttaraya and others were the Devas.
The seven Rishis were Hiranya-romay, Vedasiras, Urddhabâhu and others.
The presiding deity of Vaikuntha incarnated in partial manifestation as the son of Subhra and Vikuntha. He was the Avatâra of this Manvantarâ. [This is the first half of the Third Round. The incarnation of the Lord of Vaikuntha may have some significance, but what is not clear from the text.]
