When sacrifices and religious rites are made its upastha, shame its varutha, Upaya and Apaya its kuvara, the breath called Apana its aksha, the breath called Prana its yuga, knowledge and the allotted period of existence its points for tying the steeds, heedfulness its handsome vandhura, the assumption of good behaviour its nemi, vision, touch, scent, and hearing its four steeds, wisdom its nabhi, all the scriptures its pratoda, certain knowledge of the scriptural declarations its driver, the soul its firmly-seated rider, faith and self-restraint its fore-runners, renunciation its inseparable companion following behind and bent upon doing it good, purity the path along which it goes, meditation (or union with Brahma) its goal, then may that car reach Brahma and shine there in effulgence.[906] I shall now tell thee the speedy means that should be adopted by the person who would equip his car in such a fashion for passing through this wilderness of the world in order to reach the goal constituted by Brahma that is above decrepitude and destruction. To set the mind upon one thing at a time is called Dharana.[907] The Yogin observing proper vows and restraints, practises in all seven kinds of Dharana. There are, again, as many kinds of Dharanas arising out of these, upon subjects that are near or remote.[908] Through these the Yogin gradually acquires mastery over Earth, Wind, Space, Water, Fire, Consciousness, and Understanding. After this he gradually acquires mastery over the Unmanifest.[909] I shall now describe to thee the conceptions in their order that are realised by particular individuals amongst those that are engaged in yoga according to the rules and ordinances that have been laid down. I shall tell thee also of the nature of the success that attaches to yoga commenced (according to rules) by him who looks within his own self.
