If Ego Death, Near-Death, and Death are all somewhat similar to a point, then we can learn about what what after-death feels like with large doses of psychedelics. Not saying you should…. in fact, only people with shamanic-leaning personalities should really do that… but they can do it, and come back and tell us what they went through, for the benefit of all.
And if what occurs during such an experience does really mimic death (and of course there’s no way to know for sure), then we know this:
You will have total free will in almost all conceivable dimensions. Negatively, you may feel chaotic and confused, and ready (and afraid) to split apart into billions of pieces, which you may fear will not want to reassemble. That fear will be extremely short lived, as fear is probably a product of ego.
You then literally will explode into a billion pieces, but then you’ll notice you’re still there. You’ll notice, that whatever you do, you’re still there. There is no escape from the consciousness, except for the conscious decision to go void. That option will always be there, and it’s not permanent, so use it as a resting option, anytime, after your body is gone.
You will then notice that you are both the symphony of life, as well as just a piece of that symphony, paradoxically at the same time.
The heaviness of 3-D reality will drain from your spirit. There will be no more tension. No more muscle pain, no more mental pain, no more pain. No need to go pee. No dry mouth. No bodily worries, whatsoever.
You will have the choice of dancing in the cosmos of spirit, joining the sound and movements your spirit makes, with the sound and movements of what used to be others.
Or you may come back. Earth dimensional reality is the hardest and slowest part of eternal life, but you are welcome back to it anytime, and all the drama that comes with it.
