Mbh 5.27.1c

And these persons who are now assisting you, have been always obedient to you,--this Krishna, and Satyaki, and Virata of the golden car, of Matsya land, with his son at the head of martial warriors. All the kings, formerly vanquished by you would have espoused your cause at first. Possessed of mighty resources, dreaded by all, having an army, and followed behind by Krishna and Arjuna, you might have slain your foremost of foes on the field of battle. You might have (then) brought low Duryodhana’s pride. O Pandava, why have you allowed your foes to grow so powerful? Why have you weakened your friends? Why have you sojourned in the woods for years and years? Why are you now desirous of fighting, having let the proper opportunity slip? An unwise or an unrighteous man may win prosperity by means of fighting; but a wise and a righteous man, were he free from pride to betake to fight (against better instinct), doth only fall away from a prosperous path. O Pritha’s son, your understanding inclines not to an unrighteous course. From wrath you ever committed a sinful act. Then what is the cause, and what is the reason, for which you are now intent to do this deed, against the dictates of wisdom? Wrath, O mighty king, is a bitter drug, though it has nothing to do with disease; it brings on a disease of the head, robs one of his fair fame, and leads to sinful acts. It is drunk up (controlled) by those that are righteous and not by those that are unrighteous. I ask you to swallow it and to desist from war. Who would incline himself to wrath which leads to sin? Forbearance would be more beneficial to you than love of enjoyments where Bhishma would be slain, and Drona with his son, and Kripa, and Somadatta’s son, and Vikarna and Vivinsati, and Karna and Duryodhana. Having slain all these, what bliss may that be, O Pritha’s son, which you will get? Tell me that!
