I think that depends on your worldview - as you mentioned really. I don’t believe in divinity or gods myself. I do believe that entities exists that humans call dogs and label as “the divine”, but these are just different manifestations of spirit, they are not so much “higher” or “better” but they can be more experienced in terms off timelines. I have a picture that is more like, a large spirit manifests into many smaller manifestations, incarnate or not, to experience more.
I think that even our higher selves, which could have thousands of incarnation - just on Earth - and many more as other formats of spirits and on other planets, are themselves manifestations of a larger being.
But that’s me and my meditations, I tend to look at things detached from the idea of being one human personality on Earth as if that was all there is. I did too many past life “regressions” and found to many non-humans and animals on Earth and other planets to see myself as just this one human now.
I don’t actually believe this is possible, because if we have a higher self (also called an oversoul) that we are a manifestation of, when we remember being that higher self, and all the other selves, and there is SO much more to us, we also realize the whole gestalt being has a say, not just the one personality out of thousands. We also remember incarnation has nothing to do with the random entities we worship.
I actually have revised my concept of reincarnation, which is not that we are one person redoing anything - we are all just that one aspect of self, unique and … I think it’s not directly repeated. We - the actual we not the human we - curate a subset of our energy to invest in an incarnation, and each incarnation gets it’s own design. It’s not random. I guess it could repeat the effort for a different environment, but I no longer see reincarnation like a chain of incarnations of the same person. It’s more like a hub with spokes and we can all remember each other as all being our “past” lives.
So the RHP thing is really very egocentric. That is because it’s assuming this personality is paramount and alone when it is not, it’s part of a bigger organized being that is not beholden to any Earth “god” - though lots of it’s incarnations probably do worship something if they want to in whatever timeline they incarnated into.
And I think that, if that base assumption (small me is all there is) is wrong, nothing else about “ego death and joining with source” makes sense with that in question.
I think what we actually do, and this is based on my own travels and verified (for me) by the writings of several shamanic adepts including Robert Munroe, Robert Moss, The taoists, Gurdjieff, that what the religious will often do, is spend time in an astral location we think is some religion’s afterlife, because we get what we expect, and after we get bored of that we’ll go on with the spiritual journey as a whole being.
