Mbh 8.35.3a

"Sanjaya said, 'Unto the ruler of the Madras who was speaking in that strain, that chastiser of foes, viz., thy mighty-armed son of cheerful soul replied, saying, "Do not, O mighty-armed one, think disparagingly of Karna, otherwise called Vaikartana, in battle,--that warrior who is the foremost of all wielders of arms and who is acquainted with the meaning of the whole body of our scriptures. Hearing the terrible and loud twang of his bow and the sound of his palms, the Pandava troops fly away on all sides. Thou hast witnessed it with thy own eyes, O mighty-armed one, how Ghatotkaca, screened by his illusions and displaying hundreds of illusions, was still slain that night (by Karna). Feeling a great fear all these days Vibhatsu could never stand, fronting Karna. The mighty Bhimasena also, moved hither and thither by the horn of Karna's bow, was, O king, addressed in very harsh words such as 'Fool' and 'Glutton.' The two brave sons of Madri also were defeated by Karna in great battle, though, from some object he had in view, he did not, O sire, slay them then. That foremost one of Vrishni's race, viz., the heroic Satyaki, the chief of the Satwata clan, was vanquished by Karna and made carless. Others, such as all the Srinjayas headed by Dhrishtadyumna, have been repeatedly defeated in battle by Karna the great car-warrior who has achieved all these feats and who excited with wrath, is competent to slay Purandara himself armed with the thunderbolt in fight. Thyself also, O hero, art acquainted with every weapon. Thou art, again, the master of all branches of learning. There is none on Earth who is thy equal in might of arms. Irresistible in prowess, thou art like a dart (Shalya) unto thy enemies. It is for this, O king, that thou O slayer of foes, art called 'Shalya.' Encountering the might of thy arms, all the Satwatas were unable to get the better of it. Is Krishna superior to thee in might of arms, O king?
