The cure most often refused is the one small enough to insult the person who needs it.
A belief about one's own standing decides what a person will consent to do, and that consent decides whether a method ever gets run at all. Rank insisted the remedy be proportionate to the man; the belief produced fury, fury nearly produced a departure, and departure would have settled it for good.
What turned it was performing an unimpressive act on the word of the man of God, then performing it again after six attempts had shown nothing. Most people quit around the sixth and conclude the method was worthless, when the return on a small correction arrives all at once, long after the work that earned it. A person who will only do what feels worthy of them stays exactly as they are, and the years pass with the condition untouched.
