It must be remembered that the involuntary muscles which move the heart, as well as the tiny muscles which form the middle-coat of the arteries and the veins, are controlled by the Sympathetic System, and thus the important work of the circulation, which goes on day and night, year in and year out, during life, is directly under the charge of the Sympathetic System and the Subconscious Mind. Also, the involuntary muscles which are concerned with the activities of the liver, the kidneys and the spleen, are under the same direct control. Dr. E. H. Pratt, in the "Series of Impersonations" above referred to, makes the "Subconscious Man" tell the following wonderful truth, which we suggest each reader read carefully and fix in his mind: "My brother the Sympathetic Man has told you that I am the animating spirit of his construction; and as he is the great body builder, having furnished the emotions under which our entire family has been put into form, you can understand by what right I pose before you as the human form of forms. All the rest of the family are because I am. Even my Conscious brother, who claims superiority to his fellow-shapes because he bosses them around a little and makes use of them, is a subject of my own creation.... I am the life of the Sympathetic Man, whose existence as a human shape has already sufficiently been well established, and as there is no part of him which is not alive, the conclusion is very evident that his shape and mine are identical. _There is no part of the sympathetic system which is not animated by my own principle of vitality._ Indeed, he is but a cup of life, though I can assure you that his cup is full, and he would not be good for much if it was not. So, if you are able to conceive the shape of the Sympathetic Man, you can regard this form as identical with my own. This is really a very modest claim on my part, and does not quite do justice to myself, for in reality the Sympathetic Man does not contain all there is of me by any means, for I am not only in him, but all around him, and he is not by any means capable of containing my full self."
