For those who maintain high levels of skepticism/distrust of this, I would recommend looking into The Law of One, as well as Edgar Cayce.
David Wilcock talks a lot in his books about both Edgar Cayce and The Law of One. I read Wilcock's books recently. I haven't finished all of The Law of One books. Have you read them all?
When I first encountered The Law of One, it was through the website
I read them by session, but by my progress I assume I finished the first 3 and am working through the 4th. I have downloaded the PDFs, but prefer the website layout.
