Mental attitude alone will not clean the watch. To concentrate on the work of housecleaning without using broom, soap and water is not sufficient. Reason and common sense teach us that the removal of physical, material encumbrances can be, to say the least, accelerated by the use of physical or physiological agents. Anyone who has observed or himself experienced the efficacy of natural diet, cold-water treatment, massage and osteopathy in dealing with the morbid accumulations in the system will never again underestimate the practical value of these "brooms." In our study of the nature and purpose of acute diseases we have found that Nature tries to purify the system from its morbid encumbrances through inflammatory, febrile processes (acute diseases) and that these cleansing efforts of Nature are generally prevented, checked and suppressed by allopathic methods of medical and surgical treatment, and thus changed into chronic disease conditions. The metaphysical healers do away with these suppressive methods of treatment and allow Nature's acute cleansing and healing efforts to run their natural course. Thus they profit by the fundamental laws of cure without understanding them. The acute disease, whose very existence they deny, is in reality the cure. Furthermore, rational mental and metaphysical treatment supports Nature's efforts actively by supplanting the weakening and paralyzing fear vibrations with relaxing and invigorating vibrations of hope, confidence and faith in the supremacy of Nature's healing forces. Under these favorable conditions, the organism will arouse itself to the purifying and constructive healing crises (the chemicalizations of Christian Science) and through these eliminate the morbid encumbrances and restore normal structure and functions. While functional disorders, in nearly every case, yield readily enough to the natural methods of living and of treatment and to the right mental attitude, it is different with organic diseases. When waste matter, ptomaines or poisonous alkaloids and acids produced in the body as a result of wrong diet and other violations of Nature's laws have brought about destruction and corrosion in vital parts and organs--when dislocations and subluxations of bony structures, or new growths and accumulations in the forms of tumors, stones or gravel obstruct the blood vessels and nerve currents, shut off the supply of the vital fluids and thus cause malnutrition and gradual decay of the tissues--when, in addition to this, the organism has been poisoned or mutilated by drugs and surgical operations, then its purification and repair becomes a tedious and difficult task. Not only must the mechanism of the body be cleansed and freed from obstructive and destructive materials, but the injured parts must be repaired, morbid growths and abnormal formations dissolved and eliminated and lesions in the bony structures corrected by manipulative treatment.
