"Thus did the blessed Hari assume in days of old that grand form having the equine head. This, of all his forms, endued with puissance, is celebrated as the most ancient. That person who frequently listens or mentally recites this history of the assumption by Narayana of the form equipt with the equine head, will never forget his Vedic or other lore. Having adored with the austerest penances the illustrious deity with the equine head, the Rishi Panchala (otherwise known as Galava) acquired the science of Krama by proceeding along the path pointed out by the deity (Rudra). I have thus recited to thee, O king the old story of Hayasiras, consistent with the Vedas about which thou hadst asked me. Whatever forms, the Supreme Deity desires to assume with a view to ordaining the various affairs of the universe, he assumes those forms immediately within himself by exercise of his own inherent powers. The Supreme Deity, endued with every prosperity, is the receptacle of the Vedas. He is the receptacle of Penances also. The puissant Hari is Yoga. He is the embodiment of the Sankhya philosophy. He is that Para Brahman of which we hear. Truth has Narayana for its refuge. Rita has Narayana for its soul. The religion of Nivritti, in which there is no return, has Narayana for its high abode. The other religion which has Pravritti for its basis, has equally Narayana for its soul. The foremost of all the attributes that belong to the element of Earth is scent. Scent has Narayana for its soul.
