Mbh 6.25.7a

“Arjuna said,--‘Beholding these kinsmen, O Krishna, assembled together and eager for the fight, my limbs become languid, and my mouth becomes dry. My body trembles, and my hair stands on end. Gandiva slips from my hand, and my skin burns. I am unable to stand (any longer); my mind seems to wander. I behold adverse omens, too, O Kesava. I do not desire victory, O Krishna, not sovereignty, nor pleasures. Of what use would sovereignty be to us, O Govinda, or enjoyments, or even life, since they, for whose sake sovereignty, enjoyments, and pleasures are desired by us, are here arrayed for battle ready to give up life and wealth, viz., preceptors, sires, sons and grandsires, maternal uncles, father-in-laws, grandsons, brother-in-laws, and kinsmen. I wish not to slay these though they slay me, O slayer of Madhu, even for the sake of the sovereignty of the three worlds, what then for the sake of (this) earth?[129] What gratification can be ours, O Janardana, by slaying the Dhartarashtras? Even if they be regarded as foes,[130] sin will overtake us if we slay them. Therefore, it behoveth us not to slay the sons of Dhritarashtra who are our own kinsmen.[131] How, O Madhava can we be happy by killing our own kinsmen? Even if these, with judgments perverted by avarice, do not see the evil that ariseth from the extermination of a race, and the sin of internecine quarrels, why should not we, O Janardana, who see the evils of the extermination of a race, learn to abstain from that sin? A race being destroyed, the eternal customs of that race are lost; and upon those customs being lost, sin overpowers the whole race. From the predominance of sin, O Krishna, the women of that race become corrupt. And the women becoming corrupt, an intermingling of castes happeneth, O descendant of Vrishni. This intermingling of castes leadeth to hell both the destroyer of the race and the race itself. The ancestors of those fall (from heaven), their rites of pinda and water ceasing.
