The man who controls the mind of another, or another's disease, through his mind, must possess the following requisites: First, health; second, will; third, faith that he can control the subject. No _reasoning_ is necessary. The less causality he possesses, the better. The less reasoning faculties, the better he can perform. Why? Animal magnetism is an animal power--not a spiritual. All the animal qualities--organs--are located in the back and lower part of the brain. They act independent of reason. Passions have no reason. The affections have no reason. Anger and hate have none. The force, driving power of man is centred back of the ears. The cerebellum, or lower brain, acts independent of reason. Birds, and most of the animals, possess all the qualities that the cerebellum of man contains. The upper brain--the cerebrum--is the instrument of our thoughts--our reason. In sleep, it is still; its action is suspended. Hence there is no reason in our dreams. The motive power is in the lower brain; hence somnambulism. If there is anything of a "trance" nature, it means shutting off the action of the cerebrum, and concentring the power in the cerebellum. Some persons have but little upper brain. If they have the other requisites, they may become good clairvoyants, or magnetizers, according to the manner in which they exercise the animal power. I have yet to find a professional clairvoyant with large or active reasoning (intellectual) qualities. YET ROOM FOR MORE DISCOVERIES. The _living_ blood has not yet been analyzed. It contains a vitalizing element which chemistry has not yet been adequate to detect. There is yet as much to be discovered in the science of life as has already been revealed to man. It will yet be found out. How is the power, or force, conveyed from the operator to the person operated upon? Through what medium does it act? Let us begin with the brain. Let us take a ball of cotton for our illustration. We draw out a piece from it, and spin it out to our fancy. It is a thread, but _cotton_ still, twisted to a fine string. The brain is located at the top of man. By means of fine threads, called nerves, the brain is distributed over the entire body, so completely that you cannot stick a pin in the flesh without touching a nerve, wounding the brain. Suspend the entire action of the brain, as by ether, chloroform, or nitrous oxygen gas, and sticking the pin is not felt. Partially suspend the action, as by a small quantity of the nitrous oxygen gas, and the force of the brain (or active force) is centred upon the lower brain, and the man under its influence acts out his animal nature in spite of reason. A man, I hold, who magnetizes or mesmerizes another, uses only the force of the lower brain. Like begets like. He cannot affect a person of large intellectual organs; only one with the animal organs active.
