Did Karna ever accept that Arjuna is better than all the past warriors? Yes. Karna had praised Arjuna multiple times. Karna praises Arjuna infront of Bhishma Other than you, who among the kings is capable of fighting with Arjuna on the field of battle? The learned ones speak about his celestial deeds. The encounter between the intelligent one and Tryambaka was superhuman. As a result of this, he obtained a boon that is difficult for those with unclean souls to get. If you permit me, | will fight with that excellent Pandava today. I am incapable of tolerating him. He is like an extremely terrible and poisonous snake which kills with its glances alone. I have placed death, or victory, at the forefront.” 980 (3), Dronabhisheka parva, Mahabharata. Karna says that Drona is incapable of defeating Arjuna Karna said, ‘Do not censure the preceptor. The brahmana is fighting to the best of his ability. In the battle, I do not think that Pandava can be defeated by Drona, though he is skilled in the use of weapons. That is the reason the one with the white horses has passed him and has penetrated. 1104 (127), Ghatotkacha Vadha parva, Mahabharata. Karna says that there has never been a warrior like Arjuna (mentioning his feats at Khandava, Hiranyapura and Virata) He is firm and accomplished in the use of weapons. He is light in the use of his hands. There is no warrior who is Pandaveya’s equal. He grasps many arrows tufted with the feathers of herons. He shoots them as if they were but one. They descend at the distance of one krosha and do not deviate from their aim. Where is the warrior on earth who is his equal? With Krishna as his second, the spirited atiratha Pandaveya satisfied the fire. The great-souled Krishna obtained the chakra there and Pandava Savyasachi the bow Gandiva. The mighty-armed one, whose spirit does not wane, also obtained the chariot, witha fierce and loud roar. It is yoked to white horses. He obtained giant quivers that are divine in form and are inexhaustible. The bearer of oblations also gave him celestial weapons. He slew the daityas in Indra’s world and destroyed all the kalakeyas in a battle. He obtained the conch shell Devadatta there. Who possesses greater fame than him on earth? He faced the immensely generous Mahadeva himself in a battle and satisfied him. He thus obtained the extremely terrible pashupata, the great weapon that can destroy the three worlds. The various guardians of the world assembled and gave him weapons that have no measure. The lion among men swiftly slew in battle the assembled kalakhanja asuras. In Virata’s city, alone on a chariot, he defeated all of us who were assembled there. He retrieved the wealth of cattle from us and robbed the maharathas of their garments. 1207 (57), Karna Vadha parva, Mahabharata.
