Perhaps...., egos/personality, souls and spirit are but ONE pure
awareness/consciousness. Egos and soul are all of the same
substances(spirit) expressed through different vehicles and/or
mediums.
Picture the simplified diagram below

Pure awareness/consciousness/Spirit is all there is around and is
symbolized by the blue background in the diagram. When without
vehicles or medium to interact/reflect, it remains in Beingness.
That could be why when no thought arises in a meditation, all that
remains is this pure undifferentiated awareness.
Subjected to the ‘encasement’ of physical/mental bodies, it becomes
Ego/personality. The bodies partially dictate what is being
reflected, thus giving rise to the holographic impression of a
physical reality and personality. Likewise in a similar manner,
Soul could be the result of consciousness being subjected to a
medium with a different range of vibration. Nevertheless,
they(ego/soul) are all one thing, which is the blue substance(pure
undifferentiated awareness/consciousness). The differences arise
because each aspect (of the ONE consciousness/awareness) is putting
attention to different focuses.
When the physical body dies, the ego disappears because its
physical hologram generator(bodies) has disintegrated. When that
happens, the awareness 'within' remembers itself as the soul or, if
other subtle bodies remained, perceive the after-death environment
accordingly.
What's your view on this?...
