The Nature of Personal Reality

"To change the physical effect you must change the original belief -- while being quite aware that for a time physical materializations of the old beliefs may still hold.

But you must not be concerned for their emergence, for this brings up the fear that the new ideas will not materialize, and so this negates your purpose."
