He was father of Vishrava and the great Rishi, Agastya. Vishrava Muni was the father of Kubera and Ravana, and all the Yaksahas are supposed to have sprung from him . Pulastya was married to one of Rishi Kardam's nine daughters named Havirbhoo. Pulastya Rishi had son Vishrava who in turn had two wives: one was Kaikesi who gave birth to Ravana, Shurpanakha, Kumbhakarna, and Vibhishana; and another was Ilavida and had a son named Kubera.
Certain sources claim that the famous granite statue of a king in Polonnaruwa, Sri Lanka, which was first thought to be of King Parakramabahu the Great, might actually be the Pulastya Rishi. This idea was later proven to be false by Prof. Senarath Paranawithana. Apart from this, no other statues, carvings, paintings or friezes of Pulastya Rishi have been found on the island.(Sri Lanka)
