FWIW, I read it back in the mid-80's during the early stages of my esoteric quest. At first, I was interested and it kept my attention - the further I went with it, the more I came away with an impression that I had just wasted a big chunk of time. Frankly, I can't recall much of it now, though what does stick is the overly religious theme throughout it.
I don't think I have the book any longer but I might have a completely different take on it now, if I were to re-read it.
