Penances set the self-restrained man having the mastery over all his senses on the way to heaven. It was through penances that the puissant Lord of all creatures, O, king, observing vows at particular intervals created all existent objects. The Adityas, the Vasus, the Rudras, Agni, the Aswins, the Maruts, the Viswedevas, the Saddhyas, the Pitris, the Maruts, the Yakshas, the Rakshasas, the Gandharvas, the Siddhas and the other denizens of heaven, and, indeed, all other celestials whatever, O child, have all been crowned with success through their penances. Those Brahmanas whom Brahmana created at the outset, succeeded through their penances in honouring not the Earth alone but the heaven also in which they roved at pleasure. In this world of mortals, they that are kings, and those others that are householders born in high families, have all become what they are only in consequence of their penances. The silken robes they wear, the excellent ornaments that adorn their persons, the animals and vehicles they ride, and the seats they use are all the result of their penances. The many charming and beautiful women, numbering by thousands, that they enjoy, and their residence in palatial mansions, are all due to their penances. Costly beds and diverse kinds of delicious viands become theirs that act righteously. There is nothing in the three worlds, O scorcher of foes, that penances cannot attain.
