Mbh 5.129.1

Vaisampayana said, “Hearing these words of Krishna, king Dhritarashtra lost no time in addressing Vidura, who was conversant with all dictates of virtue. And the king said, ‘Go, O child, unto Gandhari, possessed of great wisdom and foresight and bring her hither. With her I will solicit this wicked-hearted (son of mine). If she can pacify this wicked wretch, of evil heart, we may yet be able to act according to the words of our friend Krishna. It may be that speaking words in recommendation of peace, she may yet succeed in pointing out the right path to this fool, afflicted by avarice and having wicked allies. If she can dispel this great and dreadful calamity (about to be) occasioned by Duryodhana, it will then conduce to the attainment and preservation of happiness and peace for ever and ever.’ Hearing these words of the king, Vidura, at Dhritarashtra’s command, brought (thither) Gandhari, possessed of great foresight. And Dhritarashtra then addressed Gandhari and said, ‘Behold, O Gandhari, this thy son of wicked soul, transgressing all my commands, is about to sacrifice both sovereignty and life in consequence of his lust for sovereignty. Of wicked soul and little understanding, he hath, like one of uncultivated mind, left the court, with his sinful counsellors, disregarding his superiors and setting at naught the words of his well-wishers.’”
