ākāśaṃ caiva bhūtādir grasate taṃ tathā mahān
mahāntam ebhiḥ sahitaṃ prakṛtir grasate dvija //

The investure of water is drunk up by fire: the stratum of fire is absorbed by that of air: air blends itself with ether: the primary element of egotism devours the ether, and is itself taken up by intellect, which, along with all these, is seized upon by nature (Prakriti). Equilibrium of the three properties, without excess or deficiency, is called nature (Prakriti), origin (Hetu), the chief principle (Pradhańa), cause (Kárańa), supreme (Param). This Prakriti is essentially the same, whether discrete or indiscrete; only that which is discrete is finally lost or absorbed in the indiscrete. Spirit also, which is one, pure, imperishable, eternal, all-pervading, is a portion of that supreme spirit which is all things. That spirit which is other than (embodied) spirit, in which there are no attributes of name, species, or the like--which is one with all wisdom, and is to be understood as sole existence--that is Brahma, infinite glory, supreme spirit, supreme power, Vishńu, all that is; from whence the perfect sage returns no more. Nature (Prakriti), which I have described to you as being essentially both discrete and indiscrete, and spirit (which is united with body), both resolve into supreme spirit. Supreme spirit is the upholder of all things, and the ruler of all things, and is glorified in the Vedas and in the Vedanta by the name of Vishńu.
