That which we call "God" is, paradoxically, the un-nameable, the un-knowable. the un-fathomable. The moment you name God, God becomes dead, because a name is an attempt to encapsulate not just the reality of the phenomenal world, but of the Absolute, and that simply cannot be done. The grasping, rational mind wants to turn the Absolute into a comfortable conceptual entity in order to alleviate one's metaphysical anxiety about the mystery of existence. By conceptualizing the Absolute, one can, in effect, control and predict it. In order to truly gain union with the Absolute, man should be doing exactly the opposite: emptying oneself [kenosis] of all names, all concepts, all beliefs, about the nature of the Absolute. In other words, instead of grasping via of concept and identification, one should let go. As Alan Watts tells us: "Belief clings; Faith lets go".
Once the rational, grasping mind is relaxed and quieted, another kind of conscious presence comes into play. Zen people refer to this "other mind" as Big Mind. It is Universal Mind, and it is with this view of Big Mind that there is no need to conceptualize the idea of self and other. It is in this conceptual duality that the ordinary mind concieves of an otherness it calls "God". When this conceptualizing is absent, there is no distinction between one's own mind to that of any other mind. The problem lies within the self-created concept of the self. When one comes to the realization, via of accurate seeing, that no such "self" actually exists, then no such "other" exists either.
By transforming the Absolute into a familiar human face in the figure of Jesus, Christians can feel more secure in a world they do not understand, Jesus being a symbol for a divine parent figure. In this sense, Christianity is in the child stage of development. It clings to God, while other religions let God go in order to gain divine union. That is the paradox that the Christian fails to understand. Not only does he cling to a concept of God, he clings to the flesh, even after death, wherein the flesh is resurrected on Judgment Day to be assigned to everlasting ecstasy or everlasting agony. Heaven and Hell are merely extremes of Earthly pleasure and pain.

and whose center is everywhere"
