Space is not empty. It is composed of several mediums. These mediums are 'matter-antimatter potentials' that can undergo polarizations. They especialy do so in the vicinity of charged particles. This creats literal auras around charged particles. Carefull thinking of the structure of such auras in the living bodies will show you that they form a living bodies on their own! As a carrier of consciousness in the photonic (positron-electron potential) plenum, yes, it is a light body!
Remember that during growth, the cells that once formed your 'self' turned 'inanimate' matter (the food) into cells that could then carry your 'self' consciousness. The cells in a given body has the ability to turn inanimate matter into animate matter of its kind. This happens by a process similar to formation of charged 'auras' of inanimate matter around the cells. These 'auras' then develope into a body on its own, hence growth.
Thus we see that cells has the ability to induce 'self' into the auras around them.
