The conceptual framework I keep rattling off about
says that a human being is "the impersonal consciousness of source functioning through a particular body/mind organism as personal consciousness"
"Source" is infinite potential "nothingness", and the universe is that potential manifesting in space/time
But it says that we can never "know" source in its unmanifest potential state
The best we can know is our "own" source, our personal consciousness
Formless awareness coupled with the impersonal sense of "I am"
Out of which the experience (including our body/mind organism) arises
So maybe we could say that our core "consciousness" is our soul
But it doesn't exist independent of the experience
There is no consciousness in deep sleep, and we have no way of knowing that death will be different from deep sleep
Consciousness of source needs a body/mind vehicle to function as a personal consciousness experience
So all of this is to say that in a way, the purpose of a body/mind organism is to host a "soul" (or, in the case of tulpa systems, several souls)
Without the body/mind host organism, there is no soul, just "infinite potential nothingness"
Does that make sense?
The body/mind system and consciousness sort of "give rise to each other", they're interdependent
That's why it's called a non-dual teaching
