Thus innumerable comparisons may be drawn and analogies be found, and cases cited to prove the correctness of this theory, if our space would permit it, and if it were necessary to prove by arguments and facts the truth of the unity of the all, which must be self-evident to everyone taking the trouble to seek for the answer to such questions within himself. But the highest cannot act upon the lowest without an intermediary link connecting them, the spirit cannot act upon the body without the connecting link of the soul, nor the soul upon the body except by means of the life. We cannot cook a dish of soup for a starving beggar by means of the fire of love; but love moves the will and induces actions which the mind directs, and thus the soup may be cooked after all owing to the power of love or charity. The greatest difficulty in the understanding of occult laws arises from the circumstance that we cannot perceive remote causes or seek to connect them with ultimate effects without being able to see through the intricate network of intermediary causes between the two ends. III.—ENS NATURAE. _Diseases which have their origin in certain conditions inherent in the constitution of man._ Man is a perfect child of nature. There is not a single essence in his constitution which does not exist in nature; neither is there any substance or power to be found in nature which does not exist in him, either actually or potentially, undeveloped or developed. “There are many who say that man is a _microcosm_; but few understand what this really means. As the world is itself an organism with all its constellations, so is man a constellation (organism), a world in itself, and as the firmament (space) of the world is ruled by no creature, so the firmament which is within man (his mind) is not subject to any other creature. This firmament (sphere of mind) in man has its planets and stars (mental states), its exaltations, conjunctions and oppositions (states of feelings, thoughts, emotions, ideas, loves and hates), call them by whatever name you like, and as all the celestial bodies in space are connected with each other by invisible links, so are the organs in man not entirely independent of each other, but depend on each other to a certain extent. His heart is his {symbol}, his brain his {symbol}, the spleen his {symbol}, the liver {symbol}, the lungs {symbol}, and the kidneys {symbol}.” (“Paramirum,” III. 4.) Man has two kinds of natures. His physical organism is a product of that nature which he received from his terrestrial parents; his mental organisation is the result of a higher and quite different kind of evolution. His terrestrial nature includes not only his visible organism, but also the organisation of his astral form and his mental constitution.
