Mahabharata Vana Parva (Aranyaka Parva) Chapter 1:2
"Yudhishthira said, 'Blessed are we since the people with the Brahmanas at their head, moved by affection and compassion credit us with merits we have not. I, however, with my brothers, would ask all of you to do one thing. Ye should not, through affection and pity for us, act otherwise! Our grandfather Bhishma, the king (Dhritarashtra), Vidura, my mother and most of my well-wishers, are all in the city of Hastinapura. Therefore, if ye are minded to seek our welfare, cherish ye them with care, uniting together as they are overwhelmed with sorrow and afflictions. Grieved at our departure, ye have come far! Go ye back, and let your hearts be directed with tenderness towards the relatives I entrust to you as pledges! This, of all others, is the one act upon which my heart is set, and by doing this ye would give me great satisfaction and pay me your best regards!
"Vaisampayana continued, 'Thus exhorted by Yudhishthira the just, the people in a body set up a loud wail exclaiming,—Alas, O king! And afflicted and overwhelmed with sorrow on remembering the virtues of Pritha's son, they unwillingly retraced their steps asking leave of the Pandavas.
'The citizens having ceased to follow, the Pandavas ascended their cars, and setting out reached (the site of) the mighty banian tree called Pramana on the banks of the Ganges. And reaching the site of the banian tree about the close of the day, the heroic sons of Pandu purified themselves by touching the sacred water, and passed the night there. And afflicted with woe they spent that night taking water alone as their sole sustenance. Certain Brahmanas belonging to both classes, viz., those that maintained the sacrificial fire and those that maintained it not, who had, with their disciples and relatives, out of affection followed the Pandavas thither also passed the night with them. And surrounded by those utterers of Brahma, the king shone resplendent in their midst. And that evening, at once beautiful and terrible, those Brahmanas having lighted their (sacred) fires, began to chant the Vedas and hold mutual converse. And those foremost of Brahmanas, with swan-sweet voices spent the night, comforting that best of Kurus—the king."
