Mahabharata Anushasna Parva Chapter 107:8

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 107:8 That man who having fasted for eight and twenty days eats a single meal on the twenty-ninth day, and bears himself in this way for a full year, adhering all the while to truthfulness of speech, attains to auspicious regions of great happiness that are worshipped by celestial Rishis and royal sages. The car he obtains is endued with the effulgence of the sun and the moon, made of pure gold and adorned with every kind of gem, ridden by Apsaras and Gandharvas singing melodiously. Thereon he is attended by auspicious damsels adorned with celestial ornaments of every kind. Possessed of sweet dispositions and agreeable features, and endued with great energy, these gladden him with their company. Endued with every article of enjoyment and with great energy, and possessed of the splendour of a blazing fire, he shines like a celestial, with a celestial form having every excellence. The regions he attains are those of the Vasus and the Maruts, of the Sadhyas and the Aswins, of the Rudras and of Brahman himself. That man who having fasted for a full month takes a single meal on the first day of the following month and bears himself in this way for a full year, looking on all things with an equal eye attains to the regions of Brahman himself. There he subsists upon the succulence of ambrosia. Endued with a form of great beauty and highly agreeable to all, he shines with energy and prosperity like the sun himself of a thousand rays. Devoted to Yoga and adorned with celestial robes and garlands and smeared with celestial perfumes and unguents, he passes his time in great happiness, unacquainted with the least sorrow. He shines on his car attended by damsels that blaze forth with effulgence emitted by themselves. Those damsels, the daughters of the celestial Rishis and the Rudras, adore him with veneration. Capable of assuming diverse forms that are highly delightful and highly agreeable, their speech is characterised by diverse kinds of sweetness, and they are able to gladden the person they wait upon in diverse kinds of ways. While performing his journeys, he rides on a car that looks like the firmament itself in colour (for subtlety of the material that compose it).
