A consideration of the above will go to prove that Love (Will or Life) and Thought (Imagination or Light) are the forces by which the soul forms and regenerates the external body, and that he who obtains mastery over these forces within his own organism will be able to change and remodel his body and to cure it of all ills. The fountain of life is the will, and if the will is good and pure and not poisoned by the imagination, a pure blood and a strong and healthy body will be the result. If the imagination (thought) is pure, it will purify the will and expel from the latter the elements of evil. _The fundamental doctrine of the most rational system of medicine is therefore the purification of the Will and the Imagination_, and every one carries within his own heart the _universal panacea_, which cures all ills, if he only knows how to employ it. The purification and strengthening of the will by acts of love and human kindness and by leading a pure and unselfish life, should be the principal object of all religious and scientific education. The Bible says: "If the _salt_ (the will) of the earth is worthless, wherewith shall it be salted?" If the fountain from which all life springs is poisoned by evil thoughts, how can the soul and body be healthy? The best _blood-purifier_ is a pure will, rendered pure by pure and holy thoughts. This fundamental and self-evident truth is continually overlooked in our present age. The education of the intellect for the purpose of attaining selfish interests is made of paramount interest and the heart is neglected and left to starve.[1] The life-energy which ought to be employed to educate the heart and to render the will good and pure, is wasted in the top story of the temple of man in idle speculations about external and worthless things, in scientific quarrels and dogmatic disputations, which have usually no other object but to tickle personal vanity and to give to ignorance an external coat of learning. Many of our modern scientific authorities resemble ants, which crawl over a leaf which fell from a tree: they know all about the veins and cells of that leaf, but they know nothing whatever of the living tree, which produces such leaves, and moreover flowers and fruits. Likewise the rational medicine based upon reason and understanding, the science springing from a true knowledge of man will forever remain an enigma to the legally-authorized guardians of the health of humanity, as long as they know nothing of man except his external form and refuse to open their eyes and to see the eternal internal power, of which the external form is merely an evanescent image, a transient manifestation.
