Why is it that only Karn got three births, as Shaurya in Treta Yug, as Karn in Dwapar Yug, as Shravan in Kal Yug? The reason is his divine identity. He's the son of Mata Parvati and Mahadev. He's the God Vasusena, one who is born with wealth and knowledge. This is the tale of Parvati Nandan Vasusena.
