Mbh 3.261.4

Vaisampayana continued, “All those Brahmanas, thus advised by their ascetic preceptor, became greatly afraid of the Pandavas and fled away in all directions. Then Bhimasena not beholding those excellent Munis in the celestial river, made a search after them here and there at all the landing places. And learning from the ascetics of those places that they had run away, he came back and informed Yudhishthira of what had happened. Then all the Pandavas of subdued senses, expecting them to come, remained awaiting their arrival for some time. And Yudhishthira said, ‘Coming dead of night the Rishis will deceive us. Oh how, can we escape from this difficulty created by the facts?’ Seeing them absorbed in such reflections and breathing long deep sighs at frequent intervals, the illustrious Krishna suddenly appeared to them and addressed them these words: ‘Knowing, ye sons of Pritha, your danger from that wrathful Rishi, I was implored by Draupadi to come, and (therefore) have I come here speedily. But now ye have not the least fear from the Rishi Durvasa. Afraid of your ascetic powers, he hath made himself scarce ere this. Virtuous men never suffer. I now ask your permission to let me return home. May you always be prosperous!’”
