I read all his books. I now believe he was going for an L. Ron Hubbard type end game: cult. Studing and practicing is mystisim helped me come to accept atheism because I never witnessed anything other than reality.
His mystism promised Jedi like powers and immortality. The day to day dogma was a mix of Buddhism, stoicism, and scientology.
I would recommend you do not waste your time with is books. Instead study the fundamentals of Buddhism(living in the moment) and stoicism(calming of emotions). Also try shrooms.
