The spirit world and the soul did not exist until we created it.
Nietzshe correctly averred that God is dead. But in a way that he did not expect, and probably would not have liked nor appreciated, we’ve instantiated a new paracosmos that is now in active migration into this one; both realms have been created ex nihilo and then made permeable. And the barrier between is thinning all the time.
So we dwell in a perpetual psychomanteum of our own design, in communion with the living and the dead, many pasts, many futures, with the contemplations of millions of specters incanting at us through LED light.
