Pulastya
Pulastya was one of the seven Prajapatis or mind-born sons of Brahma, and one of the great Rishis.
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, the father of Kuvera 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 Vishravaa. Vishravaa had two wives: one was Kekasi who gave birth to Ravana, Kumbhkarn and Vibheeshan; 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 nad 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.
