Didnt mean to offend you(if I did). There is alot of folks out there with all sorts of theories and claiming they know they way ect, and they get you into that line of thinking aswell. With the endresult not being what you expected, the opposite of growth. I guess failure is also a means for growths though.
As they said in a star trek episode: its always easier believing a good lie then the truth.
Spiritual growth comes from experience, no books can provide you that.
But when it comes to intellectual growth, that im sure there are some very good options for. Im sure somebody in here will point out some good sources for that. What do you want to learn more about?
