Say you're in a classroom and the blackboard is chalked to its borders with equations. Students at the board calculate their way to answers, maybe hoping for good grades. Then someone realizes that every answer is wrong. A common error is at the root. Now what?
Simply erase the blackboard and you do little to get at the root of the trouble. But if you wipe the mistaken concept from the students' minds through good instruction you both erase the mistake and induce clarity with the same effort. It's a double action — erasing and inducing — that often comes about through a single right insight.
And this sort of double action has a parallel in the practice of spiritual healing, which involves eliminating fears or harmful misconceptions by introducing spiritual facts that underscore God's care for us. With every glimpse of God's presence, we gain confidence in His goodness. Then the incapacitating effects of fear on thought, and therefore on the body, begin to diminish.
