"Dhritarashtra said, '[I understand] that the hearts of all of you are turned towards Vikartana's son Karna, and that all of you, saw that son of Radha, that hero of the Suta caste, ever prepared to lay down his life in battle. I hope that hero of prowess incapable of being baffled, did not falsify the expectations of Duryodhana and his brothers, all of whom were then afflicted with grief and fear, and desirous of being relieved from their danger. When Bhishma, that refuge of Kauravas, was slain, could Karna, that foremost of bowmen, succeed in filling up the gap caused? Filling up that gap, could Karna fill the foe with fear? Could he also crown with fruit the hopes, entertained by my sons, of victory?'"
