That chief principle (Pradhána), which is the indiscrete cause, is called by the sages also Prakriti (nature): it is subtile, uniform, and comprehends what is and what is not (or both causes and effects); is durable, self-sustained, illimitable, undecaying, and stable; devoid of sound or touch, and possessing neither colour nor form; endowed with the three qualities (in equilibrium); the mother of the world; without beginning; and that into which all that is produced is resolved. By that principle all things were invested in the period subsequent to the last dissolution of the universe, and prior to creation. For Brahmans learned in the Vedas, and teaching truly their doctrines, explain such passages as the following as intending the production of the chief principle (Pradhána). "There was neither day nor night, nor sky nor earth, nor darkness nor light, nor any other thing, save only One, unapprehensible by intellect, or That which is Brahma and Pumán (spirit) and Pradhána (matter)." The two forms which are other than the essence of unmodified Vishńu, are Pradhána (matter) and Purusha (spirit); and his other form, by which those two are connected or separated, is called Kála (time). When discrete substance is aggregated in crude nature, as in a foregone dissolution, that dissolution is termed elemental (Prákrita). The deity as Time is without beginning, and his end is not known; and from him the revolutions of creation, continuance, and dissolution unintermittingly succeed: for when, in the latter season, the equilibrium of the qualities (Pradhána) exists, and spirit (Pumán) is detached from matter, then the form of Vishńu which is Time abides. Then the supreme Brahma, the supreme soul, the substance of the world, the lord of all creatures, the universal soul, the supreme ruler, Hari, of his own will having entered into matter and spirit, agitated the mutable and immutable principles, the season of creation being arrived, in the same manner as fragrance affects the mind from its proximity merely, and not from any immediate operation upon mind itself: so the Supreme influenced the elements of creation. Purushottama is both the agitator and the thing to be agitated; being present in the essence of matter, both when it is contracted and expanded. Vishńu, supreme over the supreme, is of the nature of discrete forms in the atomic productions, Brahmá and the rest (gods, men, &c.)
