Of the three...
A. A belief in something which lends toward success, "all things work together for good," even though it turns out to be an incorrect belief.
B. A correct belief that there is no external force (God, Karma, etc.) which protects you and "works all things for good."
C. Belief in the self to create situations which ultimately will lead to good things.
Which is the worst?
Which is the most effective?
How can you shift your core belief to one of three to maximize it's benefit? Or does that defeat the whole purpose of belief? ...to do it for purely self fulfilling purposes.
