"

Ravana's paternal grandfather, the sage Pulastya,[3] was one of the ten Prajapatis, or mind-born sons of Brahma, and one of the Saptarishi (seven great sages) in the first Manvantara (age of Manu). His maternal grandfather was Sumali (or Sumalaya), the king of the Rakshasas and the son of Sukesha. Sumali had ten sons and four daughters. Sumali wished for Kaikasi 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. Kaikasi searched among the sages and finally chose Vishrava, the father of Kubera. Ravana and his siblings were born to the couple and they completed their education from their father, with Ravana being a great scholar of the Vedas.[citation needed]
