This is Law Of One stuff, otherwise also known as the Ra material, as channeled through Edgar Cayce — of whom Wilcock believes he would be the reincarnation — in the 1960s.
Furthermore, that stuff was also already literally spoken about many years ago at the Above Top Secret forum, by someone who claimed to be an Illuminati insider who had been ordered to entertain questions from forum members for a very limited amount of time, in line with the alleged Illuminati tradition that they may do whatever they want on the condition that they disclose their intentions — albeit sufficiently cryptically, so that only the "awake & aware" would get it.
The event which was to lead to this alleged three-way split of the collective of human souls on Earth — the good go to "4D", the bad go to "4D negative", and the lukewarm go to another "3D" world, whereby Earth would regress into an earlier state of its evolution as a recovery for all of the things humanity had done to her — was supposed to be 21 December 2012, when Marduk the Destroyer would be coming back. According to this character, Marduk the Destroyer was Lucifer, in the form of the alleged Planet X, also known as Nibiru.
Said alleged Illuminati insider went by the name "Hidden Hand" over at the Above Top Secret forum, and it is by now generally accepted that the guy was just a prankster, reciting stuff from the Law Of One and other esoteric publications.
So much for Wilcock's "research".
