It is the true Alchemy of human existence, and the preventives, in each and every case must contain the spiritual correspondence to the cause they seek to remedy; and, though the followers of Hahnemann base the whole of their procedure of treatment upon their master's fundamental law of "Similia similibus curantur," yet, there may be a few rare cases wherein, this undeviating method would not apply with the required effect. In such a case, the Alchemist would resort to the well-known law of opposites, and base his treatment upon the dogma of "Contraria contrariis curantur," so long the pet theory of the Allopathic school. They work upon the hypothesis that, like attracts like, and, if disease exist, those elements must be administered to set up the vibrations that will produce the polar opposite. If the body was racked with pain, those medicines would not be given that would create or increase similar conditions, but, their antipathy would be introduced into the system or applied locally to extinguish the foe. So long as mankind remain within the semicrystallized state of soul development, so as to require the aid of external forces to support the human throne within its earthly temple, mercenary troops will exist to supply these supposed supports. Unquestionably, the astrological law is the true system of medicine, which treats disease by sympathy or by antipathy, according to the nature of the case, and the efficacy of the remedies at hand. This method is the only natural one, and has been thoroughly demonstrated by the numerous "provings of drugs" under Hahnemann's law. Happily, the time is not far distant when, the incarnated spirit will be able to use its own slumbering forces, and subdue all suffering and symptoms of disease in their very first inception, by virtue of its purer life and the dynamic potencies of its own interior, spiritual thought. Already, mental therapeutics is taking an advanced position among liberal, progressive minds, and nothing demonstrates so clearly and forcibly the grand, alchemical law of life-growth and decay, as the imponderable, invisible forces, which, constitute the materia medica, or remedial agents, of mental, magnetic, and spiritual healing.
