Once, during thirtieth kalpa named Rakta, Lord Brahma was meditating on Paramaeshthi Shiva. Suddenly a divine child appeared before him who was of red complexion and who had put on red apparels. He was none other than Lord Vamdev. Lord Brahma immediately realized the divinity of that child and was convinced that he was the embodiment of Almighty God.
Lord Brahma eulogized Vamdev who was pleased by his devotions. Four divine entities-Virija, Vivahu, Vishoka and Vishwabhavana manifested from the body of Vamdev. All of them had great resemblance to Lord Vamdev. Vamdev preached them on the finer points of religiousness so that mankind could be benefited by this knowledge.
