Sounds like.....
Norman Vincent Peal, positive thinking stuff.....basically, Hindu, the Universe is God and everything in it (including us) is part of the stuff of God, so when we "put out" good thoughts, it affects reality, Star War's, The Force is similar......basically, the antithesis to the reality of a Personal, All Powerful God controls the Universe and is NOT the Universe.....in these circles, prayer is changing the Universe (God) to mold into our needs and desires.....I'm sure some of these logic guys could drive this into the ground very quickly.....I mean, can you imagine, all of humanities thoughts, actually affecting the Universe.......talk about a mess!!!!
Like all things, the truth lies in the practical, you are going to be more productive if you are positive about life, and achieving goals, so the net result of people reading these books, can be positive in the practical sense, but devastating when you take it at the spiritual level, because it becomes the Shirley Maclain's "I'm God".
That's what it SOUNDS like to me, I haven't researched that particular book yet.
