The true scientist in the healing art is he who can take an invalid and by the use of the means at his command bring him back to health, not in an accidental manner, but in such a knowing way that he can predict the outcome. In serious cases the natural healer of intelligence and experience can do this twenty times where the man who relies on drugs does it once. The physicians who prescribe drugs are ever on the look-out for complications and relapses, and they have many of them. The natural healers know that under proper treatment neither complications nor relapses can occur, unless the disease has already advanced so far that the vital powers are exhausted before treatment is begun, and this is generally not the case. In this book many of the medical fallacies of today, both professional and lay, will be touched upon in a kindly spirit of helpfulness and ideas that contain more truth will be offered in their place. The truth is the best knowledge we have today, according to our understanding. It is not fixed, for it may be replaced by something better tomorrow. However, one fundamental truth regarding health will never change, namely, that it is necessary to conform to the laws of nature, or in other words, the laws of our being, in order to retain it. No one can cover the field of health completely, for though it is very simple, it is as big as life. The most helpful parts of this book will be those which point the way for each individual to understand his relation to what we call nature, and hence help to enable him to gain a better understanding of himself. By natural living is not meant the discarding of the graces of civilization and roaming about in adamic costume, living on the foods as they are found in forest and field, without preparation. What is meant is the adjustment of each person to his environment, or the environment to the person, until harmony or balance is established, which means health. One of the most difficult things about teaching health is that it is so very simple. People look for something mysterious. When told that good old mother nature is the only healer, they are incredulous, for they have been taught that doctors cure. When informed that they do not need medicine and that outside treatment is unnecessary, they find it difficult to believe, for disease has always called for treatment of some kind in the hands of the medical profession. When further told that they have to help themselves by living so that they will not put any obstacles in the way of normal functioning of their bodies, they think that the physician who thinks and talks that way must be a crank, and many seek help where they are told that they can obtain health from pills, powders and potions or from various inoculations and injections.
