Mbh 9.63.2b

Many were the blows of the mace, and many were the strokes of spiked bludgeons and darts and sharp arrows and lances and battle axes, that have been endured by thee! For our sake, O Krishna, thou hadst also to hear many harsh words and endure the fall, violent as the thunder, of weapons in battle! In consequence of Duryodhana's slaughter, all this has not been fruitless, O thou of unfading glory! Act thou again in such a way that the fruit of all those acts may not be destroyed! Although victory hath been ours, O Krishna, our heart, however, is yet trembling in doubt! Know, O Madhava, that Gandhari's wrath, O mighty-armed one, hath been provoked! That highly-blessed lady is always emaciating herself with the austerest of penances! Hearing of the slaughter of her sons and grandsons, she will, without doubt, consume us to ashes! It is time, O hero, I think, for pacifying her! Except thee, O foremost of men, what other person is there that is able to even behold that lady of eyes red like copper in wrath and exceedingly afflicted with the ills that have befallen her children? That thou shouldst go there, O Madhava, is what I think to be proper, for pacifying Gandhari, O chastiser of foes, who is blazing with wrath! Thou art the Creator and the Destroyer. Thou art the first cause of all the worlds thyself being eternal! By words fraught with reasons, visible and invisible that are all the result of time, thou wilt quickly, O thou of great wisdom, be able to pacify Gandhari! Our grandsire, the holy Krishna-Dvaipayana, will be there. O mighty-armed one, it is thy duty to dispel, by all means in thy power, the wrath of Gandhari!' Hearing these words of king Yudhishthira the just, the perpetuator of Yadu's race, summoning Daruka, said, 'Let my car be equipped!' Having received Keshava's command, Daruka in great haste, returned and represented unto his high-souled master that the car was ready.
