Indeed, with Krishna's help, slaying our foes headed by Karna, we are able to rule the entire earth (thus) conquered by our own arms. Endued with manliness, we are yet overwhelmed with calamities, in consequence of thy gambling vice, while the foolish null of Dhritarashtra are growing stronger with the tributes (gathered from dependent kings). O mighty monarch, it behoveth thee to keep in view the duties of the Kshatriya. O great king, it is not the duty of a Khsatriya to live in the woods. The wise are of the opinion that to rule is the foremost duty of a Kshatriya. O king, thou art conversant with Kshatriya morality. Do not, therefore, deviate from the path of duty. Turning away from the woods, let us, summoning Partha and Janardana, slay, O king, the sons of Dhritarashtra, even before the twelve years are complete. O illustrious monarch O king of kings, even if these Dhartarashtras be surrounded by soldiers in array of battle, I shall send them to the other world by dint of might alone. I shall slay all the sons of Dhritarashtra along with the Sauvalas, indeed, Duryodhana, Karna, and any one else that will fight with me. And after I shall have slain all our foes, thou mayst come back unto the woods. By acting thus, O king, no fault will be thine. (Or if any sin be thine), O represser of foes, O mighty monarch, washing it off, O sire, by various sacrifices, we may ascend to a superior heaven.
