About Saptarishi Pulastya
Pulastya (Tamil: Pulattiyan, Thai: ท้าวจตุรพักตร์) was one of the ten Prajapati or mind-born sons ofBrahma, and one of the Saptarishis (Seven Great Sages Rishi) in the first Manvantara. He was the medium through which some of the Puranas were communicated to man. He received the Vishnu Purana from Brahma and communicated it to Parashara, who made it known to mankind. He was father of Visravas who was the father of Kubera and Ravana, and all the Rakshasas are supposed to have sprung from him. Pulastya Rishi was married to one of Kardam ji's nine daughters named Havirbhoo. Pulastya Rishi had two sons - Maharshi Agastya and Visravas. Vishravaa had two wives: one was Kekasi who gave birth to Ravana, Kumbhkarn and Vibhishana; and another was Idvidaa and had a son named Kuber. Idvidaa was the daughter of Trinbindu and Alambushaa Apsaraa in the lineage of Marutt who was a Chakravartee Raajaa and was in the lineage of Vaivaswat Manu Shraadhdev. He had all gold pots in his Yagya and he gave so much to Brahmin that they left many things there only. This was the same gold which Yudhishthira took and used for his Yagya. Trinbindu was in the lineage of Marutt.
