The divine pattern and potential matter, both of which derived are from GOD; who is the beginning, the middle and the end, are Brahma, Vishnu and Shiva.
God with creative ideas is Brahma, and who pours out his love and patience is Vishnu. When the conceptual becomes cosmic, God is represented by Shiva. Brahma, Vishnu and Shiva are fundamentally one though conceived in a threefold manner.
Vishnu is the internal controller who pervades the whole universe. He gathers to himself in an ever increasing measure, the position and dignity of external supreme. Krsna, the teacher of GITA, becomes identified with Vishnu, the ancient lord of the sun, and Narayana, an ancient God of cosmic character and the goal.
The real is the supracosmic, eternal, space less Brahman who supports this cosmic manifestation in space and time. He is the universal spirit, paramatman, who ensouls the cosmic forms and movements. He fills our being, illumines our understanding and sets in motion its hidden springs.
Though God controls it, he too has the element of negativity or Maya. He puts forth his active nature and controls the souls who work out their destinies along lines determined by their own natures. God is impersonal Absolute as well as the immanent will; He is uncaused cause, the unmoved mover. The boundless universe in an endless space and time rests in Him and not Him in it.
