Since man degenerated thru civilization, he no longer knows what to do when he becomes sick. Disease remains the same mystery to modern medical science as it was to the “Medicine Man” of thousands of years ago the main difference being that the “germ” theory has replaced the “Demon” and that mysterious outside power still remains to harm you and destroy life.
Disease is a mystery to you as well as to every doctor who has not as yet looked into the “magic mirror,” which I am about to explain. Naturopathy deserves full credit for having proven that disease is within you a foreign matter which has weight, and which must be eliminated. If you want to become your own physician, or, if you are a Drugless Healer and want more success, you must learn the truth and know what disease is. You cannot heal yourst1f, or other people, without an exact diagnosis which will give you a clear idea of true conditions. This infallible truth can be learned only from the book of Nature, that is, thru a test on your own body or the “magic mirror,” as I have designated it. The safferer from any kind of diseaseor any person, whether sick or not who will go thru this healing process
of fasting and mucusless diet, will eliminate mucus thereby demonstrating that the basic cause of all latent diseases of man is a clogged up tissue system of uneliminated, un-used and un-digested food substances. Thru the “magic mirror” a true and unfailing diagnosis
of your disease is furnished, as never before.

“The Magic Mirror”
Proof that your personal, individual symptom, sore, or sensation, according to what your disease is named, is nothing more than an extraordinary local accumulation of waste. The coated tongue is evidence of a constitutional encumbrance thru out the entire system, which obstructs and congests the circulation by dissolved mucus, and this mucus even appears in the urine. The presence of unevacuated feces, retained thru sticky mucus in the pockets of the intestines, constantly poisoning, and thereby interfering with proper digestion and blood building.
To look inside your bodyfar better and clearer than can be done by doctors with expensive X-ray apparatus and learn the cause of your disease, or even discover some hitherto unknown physical imperfection or mental condition, try this:

Fast one or two days, or eat fruits only (such as oranges, apples, or any Juicy fruit in season) for two or three days, and you will notice that your tongue will become heavily coated. \X7hen this happens to the acutely sick, the doctor’s conclusion is always”indigestion.” The tongue is the mirror not oniy of the stomach, but 0f the entire membrane system, as well. The fact that this heavy coating returns, even if removed by a tongue scraper once or twice a day, is an accurate indication of the amount of filth, mucus and other poisons accumulated in the tissues of your entire system, now being eliminated on the inside surface of the stomach, intestines and from every cavity of your body. You will become further convinced of this fact of this diagnosis of your disease by another surprise in store for you; if you will empty your intestines both before and after the test.
During the Fast you are truly on Nature’s operating table without the use of a knife! The cleansing eliminating process begins immediately and the knowledge contained in these lessons provide the needed information necessary to secure the desired results.
After you have fasted, it is advisable to decrease the quantity of your customary amount of food and eat only natural, cleansing, muscusless foods (fruits and starchiess vegetables), thereby affording the body an opportunity to loosen and eliminate mucus, which is, in fact, THE HEALING PROCESS.
This “mirror” on the tongue’s surface reveals to the observer the amount of encumbrance that has been clogging up the system since childhood, thru wrong mucusforming foods. After observing the urine during this test, by allowing it to stand for a few hours, you will note the elimination of quantities of mucus in same. The actual amount of filth and waste, which is the “mysterious” cause of your “trouble,” is almost unbelievable. Diseaseevery diseaseis, first, a special, local constipation of the circulation, tissues, pipe system. The manifestation
of symptoms, or of the different symptoms. If painful and inflamed, it is from over-pressureheat or inflammation caused from friction and congestion. Second, diseaseevery diseaseis constitutional constipation. The entire human pipe system, especially the
microscopically small capillaries are “chronically” constipated, through the wrong food of civilization. White blood corpuscles are wasteand there is no man in Western civilization who has mucus-free blood and mucus-free blood vessels. It is like the soot in a stovepipe which has never been cleaned; in fact, worse, because the waste from protein and starchy foods is STICKY. The characteristics of tissue construction, especially of the important internal organs, such as the lungs, kidneys, all glands, etc., are very much similar to those of a sponge. Imagine a sponge soaked in paste or glue! Naturopathy must more and more, cleanse its science from medical superstitions, wrongly called “scientific diagnosis.” Nature alone is the teacher of a standard science of truth. She heals thru one thing FASTING every disease that it is possible to heal. This alone is proof that Nature recognizes but one disease, and that in every body the largest factors are always waste, foreign matter and mucus (besides uric acid and other toxemias, and, very often, pusif tissues are decomposed).
In order to realize how terribly clogged up the human body is, one must have seen thousands of fasters as I have. The almost inconceivable fact is, how can such quantities of waste be stored up in the body? Have you ever stopped to realize the masses of phlegm you expel during a cold? And just as it is taking place in your head, your bronchial tubes, lungs, stomach, kidneys, bladder,
etc., have the same appearance. All are in the same condition. And the spongy organ known as the tongue accurately mirrors on its surface the appearance of every other part of your body. Medicine has devised a “special science” of laboratory tests, urinal diagnosis and blood tests. More than fifty years ago, the most prominent pioneers of Naturopathy said: “Every disease is foreign matter- waste.” I said twenty years ago, and repeat it again and again, that most of these foreign matters are paste produced from wrong foods, decomposedto be seen when it leaves the body as mucus. Meat decomposes into pus. The light of truth dawned upon me after I had fasted, against the will of the Naturopath from whom I was taking treatments for Bright’s disease. ‘When the test-tube filled up with albumen, I read his thoughts in his facial expression. But to me it proved that whatever Nature expelseliminatesis waste; whether it be albumen, sugar, mineral salt or uric acid. This occurred more than twenty-four years ago, but this Nature-doctor (a former M.D.) still believes in the replacement of albumen by – high protein food& The medical diagnosis of Bright’s disease, when the chemical test of urine shows a high percentage of albumen, is as misleading as others. The elimination of albumen proves that the body does not need it, that it is over-fed, over-loaded with high protein stuff. Instead of decreasing these poison producing foods, they are Wrotjgly  increased, endeavoring to replace the “loss,” until the patient dies.
How tragic to replace waste, while Nature is endeavoring to save you, by removing it! The next important laboratory test is that of sugar in the urine, Diabetes. The medical dictionary still calls it “mysterious?’ Instead of eating natural sweets, which go into the blood, and which can be used, the diabetic patient is fed eggs, meat, bacon, etc., and, in fact, actually starves to death thru lack of natural, sugar-containing and sugarproducing foods, which have been withheld. It has long since been proven that all of these blood tests, especially the Wasserrnann test, are a fallacy. We, as Naturopaths, cannot ignore Nature’s teaching, in any way, even tho we may find it difficult to discard old errors hammered into us since childhood. One of the most misleading errors is the individual naming of all diseases. The name of any disease is not important, and not of any value whatsoever when starting a natural cure, especially thru fastings and diet. If every disease is caused thru foreign matters (and it most assuredly is) then it is only important and necessary to know how great and how much the amount of the patient’s encumbrance actually ishow far and how much his system is clogged up by foreign matters, and how much his vitality has become lowered (see Lesson 5), and, in case of tuberculosis or cancer, if the tissues themselves are
decomposed. (Pus and germs.) I have had hundreds of cases tell me that every doctor they called upon gave a different diagnosis, and a correspondingly different name for their ailment. I always surprise them by saying, “I know exactly what ails you, thru facial diagnosis, and you will see it yourself in the ‘magic mirror’ within a few days.”
The Experimental Diagnosis
Just as I have already stated in the beginning of this lesson, you must fast for two or three days. in the case of a fatty type, liquids should be used during the fast. The surface of the tongue will clearly indicate the appearance on the inside of the body, and the patient’s breath
will prove the amount and grade of decomposition. It is even possible to tell the kind of food they preferred most! Should pain be felt at any one place during the begin. ning of the fast, you may be sure that this is a weak point and the symptom is not sufficiently developed for medical doctors to reveal it thru their examination. Waste will show up in the urine with clouds of mucus, and mucus will be expelled from the nose, throat and lungs as well as in the feces. The weaker and more miserable the patient may feel during the fast, the greater is his encumbrance, and the weaker his vitality. This experimental diagnosis tells you exactly what the trouble is, and how to correct it by starting with a moderate transition diet or a more radical one and whether to continue or discontinue the fast. This experiment is the foundation, the basis of the development of the science of Nature cure, physics, chemistry, etc. It is the question put to Nature, and she replies with the same infallible answer, always and everywhere. If the patient becomes nervous, or symptoms of heart trouble occur, you may be sure that he has drugs stored up in his body. A consumptive patient starts with such terrible elimination, after a short fast, that it must be plain to all how ignorant and how impossible it is to try and cure him with good nourishing foods, such as eggs and milk.
The above explanation is the experimental diagnosis, and the only scientific one. You cannot secure a better view inside than by this simple method. No expensive apparatus can show more accurately the exact conditions as they exist inside the body. All other examinations, including iris.diagnosis, diagnosis of the spine, etc., are never exact and, therefore, not dependable. Nature’s mirrors, her revelations, her demonstrations of and by phenomenaare “magic” only so long as you lack the correct interpretation of them. Nature shows and plainly reveals to you everything, far more exact, perfect and better than all “science of diagnosis” put together.
The Prognosis of Disease
And now we come to the prognosis of disease. We hear of “latent” disease. Everyone, no matter to what extent he may enjoy “good health,” has a latent sickness, and Nature only awaits an opportunity to eliminate the waste stored up since childhood and on. Everyone knows, but fails to understand, that a severe “shock,” such as a cold or “influenza” over the entire body, starts an elimination; but, unfortunately, Nature is handicapped in her attempted housecleaning, thru the doctor’s advice to continue eating, thru the use of drugs,
etc., obstructing elimination and producing acute and chronic diseases, Anyone, even tho not sick especially in the critical age between thirty and forty may fast a few days, and thru the “magic mirror,” learn the extent of his latent disease; where his weak point is located, as well as the name of his latent disease, and where it will appear. That is the prognosis of disease, and if life insurance companies would
only believe in it, would furnish a true and safe method of determining “risks.” Fasting until the tongue is dean is dangerous. Who can
explain why the tongue becomes dean after breaking a short fast with a “square” meal, and why the “magic mirror” shows up more waste, if you live on fruits or mucusless diei, after the fast? This is the hitherto unexplained mystery of the “magic mirror.” And the simple
explanation is that the elimination is stopped for a while, thru the eating of wrong foods, and as a result you feel better for a tune with wrong foods than with fruits. And during this period even the “magic mirror” apparently misleads you into thinking the body is clean. A return to natural foods soon proves otherwise. For the ordinary person it will require from one to three years of systematically continued fastings and natural, cleansing diet, before the body is actually cleansed of “foreign matters.” You may then see how the body is
constantly eliminating waste, thru the entire outside surface of the body, from every pore of the skin, the urinal canal and the colon, from the eyes and ears, and from the nose and throat. You can see how wet as well as dried mucus (dandruff, for instance) is being expelled. All diseases, therefore, are immense quantities of waste, “chronically” stored up and, thru this artificial elimination of “chronic disease” you will agree with me and realize that I do not exaggerate when I state: The diagnosis of your diseaseof all diseases of mankind
both mental and physical, since the beginning of civilization, proves that they all have the same foundational causewhatever the symptoms may be. It is, without exception, one and the same general and universal conditiona one-ness of all disease, that is; waste, foreign matter, mucus and its poisons. “Internal impurity” is too mild an expression for chronic constipation, waste – filth – mucus – stench (offensive odor) or “Invisible ‘Waste,” is the true description.
