The lower levels seem to be tied to this world. People stay here because they can’t let something go. And there are worse places than here, which also seem to be tied to the planet, to this sort of convergence of solid energy which has been convulsed out of the pure energy of space.
Here is the thing: we are born and reborn until we learn needed lessons, and then we move on. We no longer have to come here. But the existence of human life on this planet, of our species, is a prerequisite to coming back. If we were to end life on Earth, human life, many spirits in the lower realms would be unable to reincarnate and complete their spiritual work. They would be trapped in limbo.
Such an event would amount to a Judgement Day, one based not on one life, but on many, many lives, hundreds, perhaps thousands of chances. It would mean such spirits would be trapped until live reevolves on Earth, if it ever does.
This is of course a nightmare scenario, and one I hope is wrong. Higher spirits, of course, would not be tied to this planet, and would suffer no difficulty.
This is an odd, weird, idea. I have a lot of them. But I thought I would put it out there. It is possible to imagine something like a Christian Apocalypse, even taking into accounts much bigger visions of God and reality.
