The Bhagavad Gita describes God as the uncreated imperishable absolute that gives rise to all of creation and exists in human beings as the individual soul, the true Self behind the ego and personality. Through the power of His divine will, He causes the birth, sustenance and dissolution of everything by altering the vibration of the very energy that makes up His undifferentiated existence in seemingly infinite ways. This is the single cosmic action which brings into existence all karma (worldly actions and their consequences). The result is that there are three levels of existence; the physical created universe, the spiritual realm and the one absolute state of being that is the origin of the other two.
