Text 8

bhavan bhismas ca karnas ca
kripas ca samitim-jayah
ashvatthama vikarnas ca
saumadattis tathaiva ca

Translation

There are personalities like you, Bhishma, Karna, Kripa, Asvatthama, Vikarna and the son of Somadatta called Bhurisrava, who are always victorious in battle.

Commentary by Srila Prabhupada

Duryodhana mentions the exceptional heroes in the battle, all of whom are ever victorious. Vikarna is the brother of Duryodhana, Asvatthama is the son of Dronacarya, 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. Kripacarya’s twin sister married Dronacarya.

Commentary by Sri Vishwanatha Chakravarthi Thakur

Saumadatti refers to Bhurisrava, the son of Somadatta.
