I don't know what to make of Danion.
What I do know - Jacob Boehme said one thing, Emmanuel Swedenborg said another, Martinez De Pasqualle said another, Louis-Claude De Saint-Martin said another, Fabre D' Olivet said another, Saint-Yves d'Alveydre said another, Rudolph Steiner said another, Max Hiendel said another, Madame Blavatsky said another, AP Sinnett said another, Alice Bailey said another, Dion Fortune said another, Aleister Crowley said another, Franz Bardon said something slightly different, Robert Bruce says something slightly different, and about the closest I see in good current correlation are guys like Nick Farrell, John Michael Greer, and perhaps my favorite and perhaps most pragmatic of the current writers and practitioners of these things - Mark Stavish. It seems like congruity has come with saturation and there's something that doesn't quite sit with this being just one narrative.
I still have to debate whether anything I see in a vivid inner vision is objectively real. I do believe, without any hesitation, that it's interior regurgitation of some type but it's tough to place it - ie. whether it's something from my reptilian or mammal brain, when I do see something with my eyes closed how much correlation it has to what kind of reality, etc.. I've had to come to accept that if I'm in a social situation and feel a presence brush with me that it's other people around me reacting to something I'm doing or did - even if they aren't directly seeing me, ie. there's some kind of subconscious filament that interacts with other people and spreads beyond the human body. Past that - dream visions can seem to deliver a plot but I'm still awaiting any concrete evidence that there anything other than my deeper mind attempting do voice its deepest desires.
As far as people having near death experiences - ie. seeing bardo (as Manly P Hall often chose the terminology) and which I think he quite fittingly described in Lectures on Ancient Philosophy as a mindless shifting back and forth between light and dark but really both in darkness and not going much of anywhere - or children having vivid past-life memories, yes I think there's evidence for that.
The challenge I'd have to give to someone like Danion Brinkley who'd assert that there's any kind of personal God that isn't us seeing a reflection of ourselves in the inner mirror - tell us something we don't know. I think the same could be said for any of the more dogmatic NDE experiencers who say yes, there's a personal God. from what I've seen that personal God tells us either things we already knew but couldn't do much with due to the realities of our lives or, on the flip, a person says that they beheld the truth of the whole universe, like Dostoevsky having a seizure halo, and when they came back they couldn't remember any of it.
Even if this is just the action of Aldus Huxley's reducing valve giving us the stingy drip of reality - just enough not to be eaten by predatory cats, bears, etc.. or walk into the spear-tip of an enemy, it says some very confusing things about the reality of a person God that can or will tell us much of anything that we don't know. While I appreciate the reports that people come back from NDE's with vastly changed perspectives, much improved health, and even enhanced degrees of psychic activity it seems like God is just as dubious and muddy a character as It was before their NDE and none of the explanations of what's happening by NDE'rs are particularly satisfying. I think my last brush with this, ie. reading Michael Newton as a prerequisite for a course, was particularly jarring in this regard because the idea seemed to be that heaven itself causes a lot of the forms of suffering that are here because people 'wanted' such experiences for spiritual growth. It makes me deeply question what moral obligations spiritual entities as such have for human beings, for example if we're souls possessing and puppeting animals are we in fact torturing animals for our own learning pleasure and our own psychodramas? Something seems more than a little twisted and questionable with that.
