When we discuss the essence of G-d, we are faced with a major problem.  We are forced to use our limited mental capacity to try to comprehend a boundless, omnipotent force.  This is not fully possible.  It is like expecting a fly to use its “brain” to solve an algebraic problem or to understand human psychology.  These phenomena are beyond the fly’s dimensions of comprehension.  Similarly, G-d is dimensions beyond what man can understand. ~ Levhavin Ulishaskel
