Perspectives

From the perspective of the lower human self (here on planet earth) any one of these bodies from the astral on up appear more powerful and freer... and could be interpreted by us as our “High Self” (it’s all relative).
Imagine you are traveling above and beyond your physical-earth body... floating into outer space you see your astral–extra-planetary bodies.... and above that is your solar–star-sun body... and above and beyond that is your etheric–galactic body... and beyond that in the empty space between galaxies is your causal–spatial bodies... and above and beyond all that is your essence or “God Self” – your universal light body.
And sitting beyond all these intermediary bodies... just beyond the expansive consciousnesses of your High Self resides the "Source" - your "Creator.

Now imagine beyond the very limits of our universe... just like the milky way galaxy contains our solar system, and our universe contains this galaxy... there is yet a whole other universe that not only encloses but has actually birthed (or “Created”) our universe... and even beyond this, there are other universes of consciousness that enclosed and birthed (and “Created”) that one, and so on up. These “parent” universes beyond ours we may call the "Super Universes".

It is possible that ones Higher Self may have been created in and originated from beyond the confines of this one provincial universe (and may perhaps still dwell there in any one of these other super universes). If your Higher Self did live in one of these other universes, it would have such an expansive view of reality (and your place in it) so far beyond the small planetary dramas you are now experiencing. On the other hand, if your Higher Self was that far off, the amount of healing work you would probably need (in order to integrate your Higher Self and your human self) could be immense - there could be any number of karmic issues and negative energies separating the two of you (so much more than the average Spirit). This is something this healing work can address. However, please understand... at those very high levels, the healing would most likely not be felt or sensed by your human self. None the less, this is work you would desperately need if you were ever going to fully integrate.
