From what I observed this is a natural consequence of starting conscious manifesting - your world starts to shake. To be completely honest, when I first came across Neville, I tossed the book aside.
It was too complicated and just too much.
But then, I think a year after that, I just had the urge to get back to it and since then I love the teachings.
What you are describing, this kind of doubt, is a very common programming we all got, probably. I mean, compare the teachings to what we all learned to be ātrueā, thatās veryā¦ far out there, to say the least. So this is natural. The best you can do is to make it a life style.
Could also be some sort of awakening. Have you thought of that?
