Arjun Vishaad Yog-Bhagavad Gita Chapter 1 [Observing the Armies on the Battlefield of Kurukshetra]
Sanjaya Said > Shaloka: 8
There are personalities like yourself, Bhisma, Karna, Krpa, Asvatthama, Vikarna, and the son of Somadatta called Bhurisrava, and who are always victorious in battle.
Duryodhana mentioned the exceptional heroes in the battle, all of whom are ever – victorious. Vikarna is the brother of Duryodhana, Asvatthama is the son of Droncarya, and Saumadatti, or Bhurisrava, is the son of the king of the Bahlikas. Karna is the half brother of Arjuna, as he was born of Kunti before her marriage with King Pandu. Krpacarya married the twin sisters of Dronacarya.
