Parva 15
Ashramavasika Parva
The old people leave Hastinapura, and one night the dead come back
Into the forest
Fifteen years passed. Dhritarashtra and Gandhari went on living in Hastinapura, among the very people who had killed their hundred sons, seeing those same faces every morning. Bhima never let them forget it, dropping some remark now and then that reminded Dhritarashtra who had killed whom, as if an old wound were never allowed to fully close.
One day Dhritarashtra said he would go to the forest. Gandhari went with him. And so did Kunti. No one had asked her to, her own sons ruled the kingdom, every comfort of the palace was hers, but she chose this herself, to live out her days with the blind couple whose sons had been killed, as though she meant to spend the rest of her life in someone else's grief. Yudhishthira tried to stop her, pleaded with her, she would not stay.
The end of Vidura
Vidura too left palace life behind and took up harsh austerities in the forest. Sometime later Yudhishthira went to see him. Vidura had grown very frail. He looked at Yudhishthira without speaking, as though words no longer served any purpose. Then he gave up his body there. The story says his radiance passed into Yudhishthira, since the two of them were tied to Dharma itself, as if two streams had finally become one.
One night's meeting
Some time after, the Pandavas went to the forest to see them. Vyasa was there. For one night he summoned back the dead, an extraordinary act, rarely repeated. That night they rose from the river, Bhishma, Drona, Karna, Abhimanyu, Draupadi's five sons, Duryodhana and his brothers, men who only the day before had thirsted for each other's blood. There was no quarrel. There were no sides. Everyone met their own, talked, recalled old times, even laughed, and returned before dawn. It is the strangest and gentlest scene in the whole Mahabharata, one night after the war in which there was no war at all.
The forest fire
Two more years passed. One day a fire broke out in the forest, spreading fast. Sanjaya was with them. Dhritarashtra told him to get out, to save himself. Sanjaya escaped, and he alone survived that fire to tell what had happened there. Dhritarashtra, Gandhari, and Kunti all died in that same fire. They made no attempt to flee, as though this ending too had been their own choice.
Note: Dhritarashtra and Gandhari going to the forest, Kunti going with them by her own choice, Vidura leaving his body, Vyasa calling up the dead for one night, all three dying in the forest fire and Sanjaya surviving it are all in the Ashramavasika Parva of Vyasa's Mahabharata. Kunti's going is her own decision in the text, not something told to her by anyone — and it is the least repeated thing in this book.
