Tricky topic, this. Time isn’t linear for spirits respective to our plane of existence. That makes piecing together a “history” a bitch. That’s problem one. Problem two is, spirits, including our little cotton pickin souls, have, by the accounts of holy men the world over in every known age, progress/have progressed/will progress/beensofarasdecidedtodowhatbelookmorelikeprogress (asynchronous time’s a bitch) through anywhere between seven and nine planes of existence, or “worlds.”
Spirits tend to be very reticent on the nature of this progression, and even when they’re not their commentaries don’t make a hell of a lot of sense to the mortal minds on our plane when they try and communicate particulars.
Best I can figure from piecing shit like this together over the course of ten years’ of hard occult study and 24 years of living deeply inundated in Divine Mystery is this:
-Our current plane of existence is either the fourth or fifth, more likely fourth, of seven worlds, or otherwise the fourth, fifth, or sixth of nine worlds.
-The Fall the and War on Heaven from judeo-christianic tradition are distorted relatings of a fight between world below and world above entities that occurred a world or two previous to our own. These fights are a common feature of each world, and the particular origin of this one, conceived of as a rebellion of somewhere between a third and half of the Host of the Words Above, is to the best of my understanding accurate.
