Mbh 6.39.2b

They (however) that are senseless and whose minds are not restrained, behold him not, even while exerting (themselves).[282] That splendour dwelling in the sun which illumines the vast universe, that (which is) in the moon, and that (which is) in the fire, know that splendour to be mine. Entering into the earth I uphold creatures by my force; and becoming the juicy moon I nourish all herbs.[283] Myself becoming the vital heat (Vaiswanara) residing in the bodies of creatures that breathe, (and) uniting with the upward and the downward life-breaths, I digest the four kinds of food.[284] I am seated in the hearts of all. From Me are memory and knowledge and the loss of both. I am the objects of knowledge to be known by (the aid of) all the Vedas. I am the author of the Vedantas, and I alone am the knower of the Vedas.[285] There are these two entities in the world, viz., the mutable and the immutable. The mutable is all (these) creatures. The unchangeable one is called the immutable.[286] But there is another, the Supreme Being, called Paramatman, who was the Eternal Lord, pervading the three worlds, sustaineth (them) (and) since I transcend the mutable, and am higher than even the immutable; for this I am celebrated in the world (among men) and in the Veda as Purushottama (the Highest Being). He who, without being deluded, knoweth Me as this Highest Being,--he knowing all, O Bharata, worshippeth Me in every way.[287] Thus, O sinless one, hath this knowledge, forming the greatest of mysteries, been declared by Me (to thee). Knowing this, O Bharata, one will become gifted with intelligence, and will have done all he needs do.’”
