Mahabharata Anushasna Parva Chapter 106:4

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 106:4 This has been said by the illustrious Angiras himself. Such a man dwells in heaven for sixty thousand years. He is roused every morning from his bed by the sweet notes of Vinas and Vallakis and flutes, O king. He who passes a whole year, drinking only a little water at the expiration of every month, acquires, O monarch, the merit of the Viswajit sacrifice. Such a man rides a chariot drawn by lions and tigers. He dwells in heaven for seventy thousand years in the enjoyment of every kind of happiness. No fast for more than a month, O chief of men, has been ordained. Even this, O son of Pritha, is the ordinance in respect of fasts that has been declared by sages conversant with duties. That man who, unafflicted by disease and free from every malady, observes a fast, verily acquires, at every step the merits that attach to Sacrifices. Such a man ascends to Heaven on a car drawn by swans. Endued with puissance, he enjoys every kind of happiness in heaven for a hundred years. A hundred Apsaras of the most beautiful features wait upon and sport with him. He is roused from his bed every morning by the sound of the Kanchis and the Nupuras of those damsels.[] Such a person rides on a car drawn by a thousand swans. Dwelling, again, in a region teeming with hundreds of the most beautiful damsels, he passes his time in great joy. The person who is desirous of heaven does not like the accession of strength when he becomes weak, or the cure of wounds when he is wounded, or the administration of healing drugs when he is ill, or soothing by others when he is angry, or the mitigation, by the expenditure of wealth, of sorrows caused by poverty. Leaving this world where he suffers only privations of every kind, he proceeds to heaven and rides on cars adorned with gold, his person embellished with ornaments of every kind.
