Indeed, he who is the invisible cause of all, who knoweth no deterioration, who is the all-pervading soul, the centre round which everything moveth, the substance in which the three attributes of Sattwa, Rajas and Tamas co-inhere, the universal soul, the immutable, the material out of which hath been created this universe, the Creator himself, the controlling lord, the invisible dweller in every object, progenitor of this universe of five elements, who is united with the six high attributes, is the Pranava or Om of the Vedas, is infinite, incapable of being moved by any force save his own will, illustrious, the embodiment of the mode of life called Sannyasa, who floated on the waters before the creation, who is the source whence hath sprung this mighty frame, who is the great combiner, the uncreate, the invisible essence of all, the great immutable, bereft of those attributes that are knowable by the senses, who is the universe itself, without beginning, birth, and decay,--is possessed of infinite wealth, that Grandsire of all creatures, became incarnate in the race of the Andhaka-Vrishnis for the increase of virtue.
