“To think what you want to think is to think TRUTH, regardless of appearances.
Every man has the natural and inherent power to think what he wants to think, but it requires far more effort to do so than it does to think the thoughts which are suggested by appearances. To think according to appearance is easy; to think truth regardless of appearances is laborious, and requires the expenditure of more power than any other work man is called upon to perform.
There is no labor from which most people shrink as they do from that of sustained and consecutive thought; it is the hardest work in the world. This is especially true when truth is contrary to appearances. Every appearance in the visible world tends to produce a corresponding form in the mind which observes it; and this can only be prevented by holding the thought of the TRUTH.”
