gaṅgāṃ devanadīṃ puṇyāṃ pāvanīmṛṣisaṃstutām |
avagāhya tu tāṃ rājā tanuṃ tatyāja mānuṣīm || 39 ||

"Thus addressed, that royal sage, viz., thy grandsire, proceeded with Dharma and all the other gods. Having bathed in the celestial river Ganga, sacred and sanctifying and ever adored by the Rishis, he cast off his human body. Assuming then a celestial form, king Yudhishthira the just, in consequence of that bath, became divested of all his enmities and grief. Surrounded by the deities, the Kuru king Yudhishthira then proceeded from that spot. He was accompanied by Dharma, and the great Rishis uttered his praises. Indeed, he reached that place where those foremost of men, those heroes, viz., the Pandavas and the Dhartarashtras, freed from (human) wrath, were enjoying each his respective status.
