There Kripa, and Kritavarma, and Drona's son, that mighty car-warrior, are protecting king Duryodhana, themselves protected by the Suta's son. There, O Krishna, Shalya, well conversant with holding the reins, looketh exceedingly resplendent as, seated on the terrace of Karna's car, he guideth that vehicle. Bear me to that mighty car-warrior, for even such is the wish cherished by me. Without slaying Karna in this battle I will never return. Otherwise, the son of Radha, O Janardana, will, in my sight, exterminate the mighty car-warriors of the Parthas and the Srinjayas." Thus addressed, Keshava quickly proceeded on his car, towards the mighty bowman Karna, for causing a single combat to take place between Karna and Savyasaci. Indeed, the mighty-armed Hari, at the command of Pandu's son, proceeded on his car, assuring (by that very act) all the Pandava troops. The rattle then of Arjuna's vehicle rose loud in that battle, resembling, O sire, the tremendous peal of Vasu's thunder. Beholding Arjuna of white steeds and having Krishna for his driver thus advance, and seeing the standard of that high-souled one, the king of the Madras, addressing Karna, said, "There cometh that car-warrior having white steeds yoked unto his vehicle and having Krishna for his driver, slaying his foes in battle. There cometh he about whom thou wert enquiring, holding his bow Gandiva. If thou canst slay him today, great good may then be done to us.
