All the marvelous works of both ancient and modern Spiritualism may have occurred, and yet none of them have been, in fact, "more than natural," however much so some minds may be accustomed to deem them. Take psychic forces as natural instrumentalities, take both embodied and disembodied intelligences who had skill and power for the control of such forces, and with these take also others who had special susceptibilities for yielding to psychic action, and you will then have in your conceptions ample natural means for the production of each and every marvel that was ever described in human history, and all such may have been produced without any more help or hindrance in kind from either God or the devil, than we all receive in the ordinary acts of daily life. Bring in what is meant by either magnetism, or mesmerism, or psychology, or psychism, or by any other term expressive of that action upon and within a human being, which lets either his own spirit-senses or the forces of some outside intelligence get play therein independent of and superior to the owner's outer or physical senses, and we then may have fitting and adequate instrumentality through which finite intelligence can legitimately produce all the marvels that human eyes have ever witnessed. Professor Cromwell F. Varley, one of England's most eminent electricians, said, when addressing a committee of the London Dialectical Society, "I believe the mesmeric trance and the spiritual trance are produced by similar means, and I believe the mesmeric and the spiritual forces are the same. They are both the action of a spirit, and the difference between the spiritual trance and the mesmeric trance I believe is this: in the mesmeric trance, the will that overpowers or entrances the patient is in a human body; in the spiritual trance, that will which overpowers the patient is not in a human body."
