Verily, there are two forms of Brahman: gross and subtle, mortal and immortal, limited and unlimited, definite and indefinite.
Yajur Veda, Brihadaranyaka Upanishad II, III-The Two Forms of Brahman, 1
The gross form is that which is other than air and akasa. It is mortal, limited and definite. The essence of that which is gross, which is mortal, which is limited and which is definite is the sun that shines, for it (the sun) is the essence of the three elements.
Yajur Veda, Brihadaranyaka Upanishad II, III-The Two Forms of Brahman, 2
Now the subtle: It is air and akasa. It is immortal, it is unlimited and it is indefinite. The essence of that which is subtle, which is immortal, which is unlimited and which is indefinite is the Person (Purusha) in the solar orb, for that Person is the essence of the two elements. This is with reference to the gods.
Yajur Veda, Brihadaranyaka Upanishad II, III-The Two Forms of Brahman, 3
May the splendor of an elephant, the greatest of all creatures, may that great glory, which was born from the Boundless, now be diffused. The Gods together have bestowed it upon me.
Atharva Veda III, 22, 1
On this splendor have all the powers of heaven concentrated their thought. May those Gods who nourish all life on earth anoint me with splendor!
Atharva Veda III, 22, 2
