There is no law of error, no principle behind problems, no definite predictable condition or disease. But this we do know; all negative mental and emotional states are destructive.
Inner torment always produces outer torment. Our brains only think in the positive. Causes and conditions always match, even though we may have trouble in unravelling them. A person who has one kind of problem usually has several. When one problem is healed at the point of cause, all of the others can be healed at the same time.
In spiritual mind treatment, the focus is never upon the problem. We focus upon the solution. A problem has no independent existence. It is merely an effect caused by something, invariably negative inner attitudes.
Focus on a positive mental state wherever possible.
