Mbh 11.14.1b

Thou wert formerly observant of the virtue of forgiveness. Why wouldst thou not observe it now? Subdue unrighteousness, O thou that art conversant with righteousness. There is victory where righteousness is. Remembering thy own righteousness and the words spoken by thyself, restrain thy wrath, O Gandhari! Do not act otherwise, O thou that art beautiful in speech.' Hearing these words, Gandhari said, 'O holy one, I do not cherish any ill feelings towards the Pandavas, nor do I wish that they should perish. In consequence, however, of grief for the death of my sons, my heart is very much agitated. I know that I should protect the Pandavas with as much care as Kunti herself protects them, and that Dhritarashtra also should protect them as I should. Through the fault of Duryodhana and of Shakuni the son of Subala, and through the action of Karna and Duhshasana, extermination of the Kurus hath taken place. In this matter the slightest blame cannot attach to Vibhatsu or to Pritha's son Vrikodara, or to Nakula or Sahadeva, or to Yudhishthira himself. While engaged in battle, the Kauravas, swelling with arrogance and pride, have fallen along with many others (that came to their aid). I am not grieved at this. But there has been one act done by Bhima in the very presence of Vasudeva (that moves my resentment). The high-souled Vrikodara, having challenged Duryodhana to a dreadful encounter with mace, and having come to know that my son, while careering in diverse kinds of motion in the battle, was superior to him in skill, struck the latter below the navel. It is this that moves my wrath. Why should heroes, for the sake of their lives, cast off obligations of duty that have been determined by high-souled persons conversant with every duty?'"
