My views are such as this:
God is everywhere, every when, and everything, nowhere, no when, and nothing. When we start to ask questions like "where" is God, we begin to put God into a space-time physical description which God is not. God is not in one location, the spirit is in all locations and since it is no thing, it is in no locations by all physical definitions.
God, in my view, is very much in the rock as well as in a human being. It is just that the human being can be aware of God in itself and its connectedness to the whole and the rock is not aware. This is because God is a breathing interconnected spirit much like a web. The spirit breathing within everything, sustaining everything. The same fundamental energy of nothingness is within the rock and is within us.
All this physical world is within what I would call the "water" or God. The "water" is this spirit and every Thing is floating around in this "water", seeing its separateness. It is all made up of this fundamental water which for all physical definitions is nothing. It is all sustained by this water since it exists within it.
Our brains are like nets fishermen use to catch fish. We catch fish and see this physical phenomenon and think this is the real, this physical thing we eat. But we miss all the water passing through our nets, the actual spirit sustaining us and making us and connecting us to everything else. In fact we are this water too but temporarily have taken the illusionary form of a net. The more we attach ourselves to this net, the more we think we are the net when in fact we are not.
How is God in us? The water is passing through us all the time already, as it is all things, all the time, in all places. The question is are you aware or conscious of the filling? Are you awakened?
