Mahabharata Anushasna Parva Chapter 107:7

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 107:7 Riding in an excellent car made of gold and possessed of great beauty and drawn by swans, he sports in joy in the company of thousands and thousands of celestial damsels. That man who having fasted for four and twenty days eats a single meal on the twenty-fifth day and bears himself thus for a full year, succeeds in obtaining a car of the foremost kind, full of every article of enjoyment. He is followed in his journeys by a large train of cars drawn by lions and tigers, and producing a rattle as deep as the roar of the clouds ridden by celestial damsels, and all made of pure gold and possessed of great beauty. Himself riding on an excellent celestial car possessed of great beauty, he resides in those regions for a thousand Kalpas, in the company of hundreds of celestial damsels, and subsisting upon the succulence of ambrosia that is sweet as nectar itself. That man who having fasted for five and twenty days eats only one meal on the twenty-sixth day, and bears himself thus for a full year in the observance of such a regulation in respect of diet, keeping his senses under control, freed from attachment (to worldly objects), and pouring libations every day on his sacred fire,—that blessed man,—worshipped by the Apsaras, attains to the regions of the seven Maruts and of the Vasus. When performing his journeys he is followed by a large train of cars made of excellent crystal and adorned with all kinds of gems, and ridden by Gandharvas and Apsaras who show him every honour. He resides in those regions, in enjoyment of such felicity, and endued with celestial energy, for two thousand Yugas. That man who having fasted for six and twenty days eats a single meal on the twenty-seventh day and bears himself in this way for a full year, pouring libations every day on his sacred fire, acquires great merit and proceeding to Heaven receives honours from the deities. Residing there, he subsists on nectar, freed from thirst of every kind, and enjoying every felicity. His soul purified of every dross and performing his journeys on a celestial car of great beauty, he lives there, O king, bearing himself after the manner of the celestial Rishis and the royal sages. Possessed of great energy, he dwells there in great happiness in the company of celestial damsels of highly agreeable manners, for three thousand Yugas and Kalpas. That man who having fasted for seven and twenty days eats a single meal on the twenty-eighth day and bears himself in this way for a full year, with soul and senses under perfect control, acquires very great merit, which, in fact, is equal to what is acquired by the celestial Rishis. Possessed of every article of enjoyment, and endued with great energy, he blazes with the effulgence of the midday sun. Sportive damsels of the most delicate features and endued with splendour of complexion, having deep bosoms, tapering thighs and full and round hips, decked with celestial ornaments, gladden him with their company while he rides on a delightful and excellent car possessed of the effulgence of the sun and equipped with every article of enjoyment, for thousands and thousands of Kalpas.
