I can see clearly now...

And what of the lenticular nature of the ego? Just how is it supposed to work and what is it's "normal" effect on our persons?

A lens that is crystal-clear, transmits energy without attenuation or affectation. It allows an interstice, or bridge, between two media such that both can remain in contact without one impinging on the other. The ego is the separator of the ethereal and the material. It is a psychic construct that is wet-wired into the human brain. It induces biochemical electrical impulses from the ethereal energy feed that it receives from our higher (more rarified) planes of existence.

Much like the piezo-electric effect of a quartz crystal, the human being has adapted this technique to provide it with a link to another realm. The ego is neither the enemy nor the obstruction. It is the asset and the ally that, once reclaimed to the essence of the person, will function effectively as originally intended. The built-in correction factors will have all been used up and removed from their obscuring presence.

Not only being useful for this effect, it will also serve the purpose of connecting our newly-minted essence to the ethereal. These processes all serve a purpose and that is to permit the evolving consciousness to remain integral to our person no matter where we continue our voyage.
