Mbh 3.197.1a

Vaisampayana said, “And the son of Pandu once more addressed Markandeya, saying, ‘Tell us again of the great good fortune of kings.’ And Markandeya said, ‘There came unto the horse-sacrifice of king Ashtaka of Viswamitra’s race, many kings. And there came unto that sacrifice the three brothers also of that king, viz., Pratardana, Vasumanas, and Sivi, the son of Usinara. And after the sacrifice was completed, Ashtaka was proceeding on his car along with his brothers when they all beheld Narada coming that way and they saluted the celestial Rishi and said unto him, ‘Ride thou on this car with us. And Narada, saying, So be it, mounted on the car, and one among those kings having gratified the holy and celestial Rishi Narada, said, O Holy One, I desire, to ask thee something.’ And the Rishi said, ‘Ask.’ And the person, thus permitted, said, ‘All four of us are blessed with long lives and have indeed every virtue. We shall, therefore, be permitted to go to a certain heaven and dwell there for a long period. Who amongst us, however, O king, shall fall down first?’ Thus questioned the Rishi said, ‘This Ashtaka shall first come down.’ And thereupon the enquirer asked, ‘For what cause?’ And the Rishi answered, ‘I lived for a few days in the abode of Ashtaka. He carried me (one day) on his car out of the town and there I beheld thousands of kine distinguished from one another by difference of hue. And beholding those kine I asked Ashtaka whose they were and Ashtaka answered me, saying, ‘I have given away these kine. By this answer he gave expression to his own praise. It is for this answer of his that Ashtaka shall have to come down.’ And after Narada had said so, one of them again enquired, saying, ‘Three of us then will stay in heaven. Amongst us three, who shall fall down first?’ And the Rishi answered, Pratardana.’ And the enquirer asked, ‘For what cause?’ And the Rishi answered, ‘I lived for some days in the abode of Pratardana also.
