Takshaka and Ashvasena were constant companions who lived in Kurukshetra on the banks of the Ikshumati (1,3). Srutasena, the younger brother of Takshaka, resided at the holy place called Mahadyumna with a view to obtaining the chiefship of the serpents (1,3). He was 4th king of Kamyaka.
According to the Shrimad Bhagavatam, Takshaka belonged to the Ikshvaku dynasty. He was a descendant of Shri Rama. The name of Takshaka's son was Brihadbala, who was killed in battle by Abhimanyu, the son of Arjuna.
Takshaka lived in the Khandava forest (1,225). Nagas lived there with other tribes like the Pisacha, Rakshasas and Daityas and Danavas (clans of Asuras ) (1,227). Arjuna burned that forest at the behest of Agni. At that time the Naga chief Takshaka was not there, having gone to Kurukshetra. But Ashvasena, the mighty son of Takshaka, was there. Arjuna slew Takshaka's wife, the mother of Ashvasena. But Ashvasena escaped (1-229,230) (4,2). To revenge upon the slaughter of his mother, Ashvasena attacked Arjuna during Kurukshetra War (8,90) (9,61), while he was battling with Karna. Ashvasena is mentioned here as born in the race of Airavata (8,90).
