Mbh 3.309.3a

Vaisampayana said, “Having felt great affliction on account of the abduction of Krishna, king Yudhishthira of unfading glory, with his brothers, left the woods of Kamyaka and returned to the delightful and picturesque Dwaitavana abounding in trees and containing delicious fruits and roots. And the sons of Pandu with their wife Krishna began to reside there, living frugally on fruits and practising rigid vows. And while those repressers of foes, the virtuous king Yudhishthira, the son of Kunti, and Bhimasena, and Arjuna, and those other sons of Pandu born of Madri, were dwelling in Dwaitavana, practising rigid vows, they underwent, for the sake of a Brahmana, great trouble, which, however, was destined to bring about their future happiness. I will tell thee all about the trouble which those foremost of Kurus underwent while living in those woods, and which in the end brought about their happiness. Do thou listen to it! Once on a time, as a deer was butting about, it chanced that the two sticks for making fire and a churning staff belonging to a Brahmana devoted to ascetic austerities, struck fast into its antlers. And, thereupon, O king, that powerful deer of exceeding fleetness with long bounds, speedily went out of the hermitage, taking those articles away. And, O foremost of Kurus, seeing those articles of his thus carried away, the Brahmana, anxious on account of his Agnihotra, quickly came before the Pandavas. And approaching without loss of time Ajatasatru seated in that forest with his brothers, the Brahmana, in great distress, spake these words, ‘As a deer was butting about, it happened, O king, that my fire-sticks and churning staff which had been placed against a large tree stuck fast to its antlers. O king, that powerful deer of exceeding fleetness hath speedily gone out of the hermitage with long bounds, taking those articles away.
