It is important to learn the exact belief that has produced disease, if you would destroy it, unless your spirituality is equal to this by holding a balance over matter; when you destroy disease in mind it disappears on the body. A surgeon must hit the ulcer with his lance to cure it, unless he is able to destroy it without the sharp point; and you must reach the mind by argument, unless the Spirit reaches it without speech. A strongly material, bigoted, or opinionated man yields more slowly to scientific treatment than the more liberal and logical mind, but the spiritual is more easily affected than either.
