Vishrava
title: Ravana text: inside his belly, thanks to a celestial boon by Brahma. Ravana was born to a great sage Vishrava (or Vesamuni), and his wife, the daitya princess Kaikeshi. People of Bisrakh village in Uttar Pradesh claim that Bisrakh was named after Vishrava, and Ravana was born there. But according to Hela historical sources and folklore, Rawana was born in Lanka, who later becomes its king. Ravana's grandfather on his father's side, the sage Pulastya, was one of the ten Prajapatis or mind-born sons of Brahma and one of the Saptarishi (Seven Great Sages Rishi) in the first Manvantara. His grandfather on title: Ravana text: his mother's side, Sumali (or Sumalaya), king of the Raksasas, was the son of Sukesha.

Sumali had wished her to marry the most powerful being in the mortal world, so as to produce an exceptional heir. He rejected the kings of the world, as they were less powerful than him.

The boys are reared as the princes of the realm, receiving instructions from the scriptures and in warfare from Vashistha.

He chooses title: Vishrava text: and his wife, Ketumati. Both sought to increase their own powers through alliances with mighty Kings and Rishis.
