excitement in the physical organs must react on the emotions.  “All modes of sensibility, whatever their origin,” says LUYS, “are physiologically transported into the sensorium.  From fiber to fiber, from sensitive element to sensitive element, our whole organism is sensitive; our whole sentient personality, in fact, is conducted just as it exists, into the plexuses of the sensorium commune.”  Therefore, if every sensation in the body acts on the brain by the aid of secondary brains or ganglions, it must be that the brain in turn can in some way act on the body.  And this has hitherto been achieved or attempted by magicians, “miracle-mongers,” thaumaturgists, mesmerists, and the like, and by the modern hypnotizer, in which we may observe that there has been at every step less and less mysticism or supernaturalism, and a far easier process or way of working.  And I believe it may be fairly admitted that in this work I have simplified the process of physically influencing mental action and rendered it easier.  The result from the above conclusions being that we can control many disorders or forms of disease.  This is an immense subject, and it would be impossible within a brief sketch to determine its limits or conditions.  That what are called nervous disorders, which are evidently the most nearly allied to emotions—­as, for instance, a headache, or other trouble induced by grief—­can be removed by joy, or some counteracting emotion or mere faith is very well known and generally believed.  But of late science has established that the affinities between the cerebral and other functions are so intimately, extensively and strangely sympathetic or identical that it is becoming impossible to say what disease may not be temporarily alleviated or cured by new discoveries in directing the nervo-mental power or will.  The Faith-Cure, Magic, Mesmerism, Religious Thaumaturgy and other systems have given us a vast number of authentic cures of very positive disorders.  But from the point of view taken by many people what has been wanting in all is, firstly, a clear and simple scientific method free from all spiritualism or wonder, and, secondly, the art of Perfecting the cures by Perseverance.  For what will relieve for an hour can be made to cure forever, if we exercise foresight and make perpetuity a part of our whole plan.

Now, as regards curing disorders, I beg the reader to specially observe that this, like many other works, depends on the state of the mind; nor can it be undertaken with hope of success unless the operator has by previous practice in easy experiments succeeded in perfectly convincing himself that he has acquired control of his will.  Thus having succeeded in willing himself to work all day without fatigue, or to pass the day without being irritable, let him begin to consider, reflect and realize that he can make himself do this or that, for the more he simply induces the belief and makes himself familiar with it, the stronger
