O thou who art attracted to the fragrant breathings of God! I have read thy letter addressed to Mrs. Lua Getsinger. Thou hast indeed examined with great care the reasons for the incursion of disease into the human body. It is certainly the case that sins are a potent cause of physical ailments. If humankind were free from the defilements of sin and waywardness, and lived according to a natural, inborn equilibrium, without following wherever their passions led, it is undeniable that diseases would no longer take the ascendant, nor diversify with such intensity. But man hath perversely continued to serve his lustful appetites, and he would not content himself with simple foods. Rather, he prepared for himself food that was compounded of many ingredients, of substances differing one from the other. With this, and with the perpetrating of vile and ignoble acts, his attention was engrossed, and he abandoned the temperance and moderation of a natural way of life. The result was the engendering of diseases both violent and diverse. For the animal, as to its body, is made up of the same constituent elements as man. Since, however, the animal contenteth itself with simple foods and striveth not to indulge its importunate urges to any great degree, and committeth no sins, its ailments relative to man’s are few. We see clearly, therefore, how powerful are sin and contumacy as pathogenic factors. And once engendered these diseases become compounded, multiply, and are transmitted to others. Such are the spiritual, inner causes of sickness. The outer, physical causal factor in disease, however, is a disturbance in the balance, the proportionate equilibrium of all those elements of which the human body is composed. To illustrate: the body of man is a compound of many constituent substances, each component being present in a prescribed amount, contributing to the essential equilibrium of the whole. So long as these constituents remain in their due proportion, according to the natural balance of the whole—that is, no component suffereth a change in its natural proportionate degree and balance, no component being either augmented or decreased—there will be no physical cause for the incursion of disease. For example, the starch component must be present to a given amount, and the sugar to a given amount. So long as each remaineth in its natural proportion to the whole, there will be no cause for the onset of disease. When, however, these constituents vary as to their natural and due amounts—that is, when they are augmented or diminished—it is certain that this will provide for the inroads of disease.
