Yes neurology is much like a river it has its main arteries that connect out in to the minute capillaries. Yes this river is carrying the spark of light an electrical impulse that is much like the same as the energy that radiates from the sun.
This energy from the sun is a river also that flows out into the biology and matter of this universe. This river is theoretically connected to the over mind of all life.
As the nerve impulse sends a signal from the tip of the finger to the brain the collective consciousness is connected back through the sun and to the over mind.
The vitamins, minerals and DNA are conduits to the river that is connected through sunshine and our own nerve impulses and the architecture of the mind is prone to providing us with the idea of an external presence.
The entire bridge to the divine is there and it requires only that we cross it and reach the other side.
Sunshine is much like a spaghetti monster... neutrinos pass through the earth in fractions of second and an entire array of light is emanated in spectrum that is perfectly adaptable by life.
Sun flairs and such provide magnetism in mass and this magnetism provides the equilibrium and flow that is between human consciousness and divine consciousness. The sun and light are surely involved on the way a divine being might interact with life.
Words make up sentences as sub atomic particles form to make up matter.
Thoughts and light are interlinked and the are uploaded to the over mind by neutrinos and even smaller forms of matter and energy.
The river is there and it is only logical to think there is a river bank and land on the other side of the stream or that the stream flows out into an ocean or that the ocean originates from a divine beginning or enlightenment.
