' Recollecting all this, O Savyasaci, quickly slay the wretched Karna in battle today. Why, O diadem-decked Arjuna, dost thou show such indifference (towards this act)? This is not the time for showing thy indifference to Karna's slaughter. That patience with which thou didst vanquish all creatures and feed Agni at Khandava, with that patience, slay thou the Suta's son. I also will crush him with my mace." Then Vasudeva, beholding Partha's shafts baffled by Karna, said unto the former, "What is this, O diadem-decked Arjuna, that Karna should succeed in crushing thy weapons today with this? Why dost thou, O hero, lose thy wits? Markest thou not that the Kauravas, (standing behind Karna), are even now shouting in joy? Indeed, all of them know that thy weapons are being baffled by Karna with his. That patience with which, Yuga after Yuga, thou hadst slain persons having the quality of darkness for their weapons, as also terrible Kshatriyas, and Asuras born of pride, in many a battle--with that patience do thou slay Karna today. Putting forth thy might, strike off the head of that foe of thine with this Sudarsana, of edge keen as a razor, that I give unto thee, like Sakra striking off the head of his foe Namuci, with the thunderbolt. That patience with which thou didst gratify the illustrious deity Mahadeva in the guise of a hunter, summoning that patience once again, O hero, slay the Suta's son with all his followers. After that, bestow upon king Yudhishthira the earth with her belt of seas, her towns and villages, and wealth, and from off whose surface all foes will have been removed. By that act, O Partha, do thou also win unrivalled fame." Thus addressed (by Krishna), the high-souled Partha of exceeding might set his heart upon the slaughter of the Suta's son.
