Mbh 5.125.1a

Vaisampayana said, “Hearing, O bull of Bharata’s race, these words of Kesava, Bhishma, the son of Santanu, then said unto vindictive Duryodhana, ‘Krishna hath spoken to thee, desirous of bringing about peace between kinsmen. O sire, follow those counsels, and do not yield to the influence of wrath. If thou dost not act, O sire, according to the words of the high-souled Kesava, neither prosperity, nor happiness nor what is for thy good, wilt thou ever have. The mighty-armed Kesava, O sire, hath said unto thee what is consistent with virtue and profit. Accept thou that object, and do not, O king, exterminate the population of the earth. This resplendent prosperity of the Bharatas amongst all the kings of the earth, thou wilt, during the very life of Dhritarashtra, destroy through thy wickedness, and thou wilt also, through this arrogant disposition of thine, deprive thyself with all thy counsellors, sons, brothers, and kinsmen, of life, if, O thou foremost of Bharata’s race, thou transgressest the words of Kesava, thy father, and of wise Vidura,--words that are consistent with truth and fraught with benefit to thyself. Be not the exterminator of thy race, be not a wicked man, let not thy heart be sinful, do not tread the path of unrighteousness. Do not sink thy father and mother into an ocean of grief.’ After Bhishma had concluded, Drona also said these words unto Duryodhana, who, filled with wrath, was then breathing heavily, ‘O sire, the words that Kesava hath spoken unto thee are fraught with virtue and profit. Santanu’s son Bhishma also hath said the same. Accept those words, O monarch. Both of them are wise, endued with great intelligence, with souls under control, desirous of doing what is for thy good, and possessed of great learning. They have said what is beneficial. Accept their words, O king, O thou possessed of great wisdom, act according to what both Krishna and Bhishma have said.
