We had no criteria, but we went into Sheol and what should we find there, but a great sprawling replica of earth! Souls had imagined and projected into their invisible existence all manner of jumbled buildings and creatures and monsters: it was a riot of imagination without Heavenly guidance, and as we suspected, there were still a majority of souls who didn't know that they were dead.

Now, we plunged into the very middle of this, trying to make ourselves as invisible as we possibly could; to conceive of ourselves as utterly without any discernible form; but this is hard. For this was a realm of the invisible; everything there was invisible. And so there we began to wander on the dreary roads in semidarkness, among the malformed, the half-formed, the unformed, the moaning and dying, and we in our angelic forms.

Nevertheless, the confused souls didn't take very much notice of us! It was as if many couldn't see clearly at all. Now, you know this state has been described by human shamans in the past, by saints, by those who have come close to death, passed through it, and then been revived and continued to live. I'm sure you've run across as much many a time.
