Virtue, Profit, Pleasure, and Salvation have all been treated in it.' After this, the lord of Uma,--the divine and multiform Siva of large eyes, the Source of all blessings, first studied and mastered it. In view, however, of the gradual decrease of the period of life of human beings, the divine Siva abridged that science of grave import compiled by Brahman. The abridgment, called Vaisalakasha, consisting of ten thousand lessons, was then received by Indra devoted to Brahman and endued with great ascetic merit. The divine Indra also abridged it into a treatise consisting of five thousand lessons and called it Vahudantaka. Afterwards the puissant Vrihaspati, by his intelligence, further abridged the work into a treatise consisting of three thousand lessons and called it Varhaspatya. Next, that preceptor of Yoga, of great celebrity, viz., Kavi of immeasurable wisdom, reduced it further into a work of a thousand lessons. In view of the period of men's lives and the general decrease (of everything), great Rishis did thus, for benefiting the world, abridge that science. The gods then, approaching that lord of creatures, viz., Vishnu, said unto him, 'Indicate, O god, that one among mortals who deserves to have superiority over the rest.' The divine and puissant Narayana, reflecting a little, created, by a fiat of his will, a son born of his energy, named Virajas. The highly blessed Virajas, however, did not desire sovereignty on earth.
