Mahabharata Udyoga Parva Chapter 72:4

Mahabharata Udyoga Parva (Bhagwat Yana Parva) Chapter 72:4 Even after slaying one's foes, repentance, O Janardana, possesseth the heart. He that surviveth among the foes giveth trouble, for the survivor, collecting a force, seeketh to destroy the surviving victor. In hopes of terminating the dispute, one often seeketh to exterminate the foe. Thus victory createth animosity, and he that is defeated liveth in sorrow. He that is peaceful, sleepeth in happiness, giving up all thoughts of victory and defeat, whereas he that hath provoked hostility always sleepeth in misery, with, indeed, an anxious heart, as if sleeping with a snake in the same room. He that exterminates seldom winneth fame. On the other hand, such a person reapeth eternal infamy in the estimation of all. Hostilities, waged over so long, cease not; for if there is even one alive in the enemy's family, narrators are never wanted to remind him of the past. Enmity, O Kesava, is never neutralised by enmity; on the other hand, it is fomented by enmity, like fire fed by clarified butter. Therefore, there can be no peace without the annihilation of one party, for flaws may always be detected of which advantage may be taken by one side or other. They that are engaged in watching for flaws have this vice. Confidence in one's own prowess troubleth the core of one's heart like an incurable disease. Without either renouncing that at once, or death, there can be no peace. It is true, O slayer of Madhu, that exterminating the foe by the very roots, may lead to good result in the shape of great prosperity, yet such an act is most cruel. The peace that may be brought about by our renouncing the kingdom is hardly different from death, which is implied by the loss of kingdom, in consequence of the design of the enemy and the utter ruin of ourselves. We do not wish to give up the kingdom, nor do we wish to see the extinction of our race. Under these circumstances, therefore, the peace that is obtained through even humiliation is the best. When these that strive for peace by all means without of course wishing for war, find conciliation fail, war becomes inevitable, and then is the time for the display of prowess. Indeed, when conciliation fails, frightful results follow. The learned have noticed all this in a canine contest. First, there comes the wagging of tails, then the bark, then the bark in reply, then the circumambulation, then the showing of teeth, then repeated roars, and then at last the fight. In such a contest, O Krishna, the dog that is stronger, vanquishing his antagonist, taketh the latter's meat. The same is exactly the case with men. There is no difference whatever. They that are powerful should be indifferent to avoid disputes with the weak who always bow down. The father, the king, and he that is venerable in years, always deserve regard. Dhritarashtra, therefore, O Janardana, is worthy of our respect and worship. But, O Madhava, Dhritarashtra's affection for his son is great. Obedient to his son, he will reject our submission. What dost thou, O Krishna, think best at this juncture? How may we, O Madhava, preserve both our interest and virtue?
