Mbh 15.33.1b

Some went to the regions of the gods, some to the region of Brahman, some to the region of Varuna, and some to the region of Kuvera. Some among those kings proceeded to the region of Surya. Amongst the Rakshasas and Pisachas some proceeded to the country of Uttara-Kurus. Others, moving in delightful attitudes, went in the company of the deities. Even thus did all those high-souled persons disappear with their vehicles and animals and with all their followers. After all of them had gone away, the great sage, who was standing in the waters of the sacred stream viz., Vyasa of great righteousness and energy, that benefactor of the Kurus, then addressed those Kshatriya ladies who had become widows, and said these words, "Let those amongst these foremost of women that are desirous of attaining to the regions acquired by their husbands cast away all sloth and quickly plunge into the sacred Bhagirathi."--Hearing these words of his, those foremost ladies, placing faith in them, took the permission of their father-in-law, and then plunged into the waters of the Bhagirathi. Freed from human bodies, those chaste ladies then proceeded, O king, with their husbands to the regions acquired by the latter. Even thus, those ladies of virtuous conduct, devoted to their husbands, entering the waters of the Bhagirathi, became freed from their mortal tenements and attained to the companionship of their husbands in the regions acquired by them. Endued with celestial forms, and adorned with celestial ornaments, and wearing celestial vestments and garlands, they proceeded to those regions where their husbands had found their abodes. Possessed of excellent behaviour and many virtues, their anxieties all dispelled, they were seen to ride on excellent cars, and endued with every accomplishment they found those regions of happiness which were theirs by right.
