Mbh 8.96.2a

"Sanjaya continued, 'Having heard these words of the high-souled Keshava, Yudhishthira, with great joy, worshipped in return that hero of Dasharha's race. "Good luck, Good luck!" were the words, O monarch, that he said. And he added, "It is not wonderful, O mighty-armed one, in thee, O son of Devaki, that Partha, having obtained thee for his charioteer, should achieve feats that are even super-human." Then that chief of Kuru's race, that righteous son of Pritha, taking hold of Keshava's right arm adorned with Angadas, and addressing both Keshava and Arjuna, said, "Narada told me that ye two are the gods Nara and Narayana, those ancient and best of Rishis, that are ever employed in the preservation of righteousness. Gifted with great intelligence, the master Krishna Dvaipayana, the highly blessed Vyasa, also hath repeatedly told me this celestial history. Through thy influence, O Krishna, this Dhananjaya the son of Pandu, facing his foes, hath vanquished them, without ever turning back from any of them. Victory, and not defeat, we are certain to have, since thou hast accepted the drivership of Partha in battle." Having said these words, king Yudhishthira the just, that tiger among men, mounting his car, adorned with gold and having steeds of ivory white and black tails and fleet as thought harnessed unto it, and surrounded by many Pandava troops, set out, conversing pleasantly with Krishna and Arjuna along the way, for beholding the field of battle on which thousands of incidents had taken place. Conversing with those two heroes, viz., Madhava and Phalguna, the king beheld Karna, that bull among men, lying on the field of battle. Indeed, king Yudhishthira beheld Karna pierced all over with arrows like a Kadamva flower with straight filaments all around its body. Yudhishthira beheld Karna illuminated by thousands of golden lamps filled with perfumed oil.
