You've talked about a transitional self...
Yes, an intermediary of sorts between our false/conditioned self and Real Self.
Real Self with a capital R..
The One Real Self, not a series of them. Maybe this transitional self could be called that operating center in us which best serves the interests of our real self, lower case. Some might call this real self the soul, the drop which ultimately becomes the Ocean.
So we're talking about that which is most aligned with Real Self, upper case.
I've also called transitional self our awakening-self and transitional ego. It could just as well be called our possible self.
Why so many terms?
To avoid fixating, getting stuck. Staying flexible but not so fluid there's nothing to work with. We still need stepping stones.
