"And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast."--_Revelation xiii. 14._ "Awake thou that sleepest, and arise from the dead."--_Ephesians v. 14._ Just where the natural and the supernatural exists is a most difficult psychological problem. Many marvellous doings and strange apparitions, from the beginning, were attributed to the supernatural. These same wonders are now known to be the application of physical and psychological laws. The "enchanters," "soothsayers," "diviners," "magicians," and "fortune tellers" have awed the simple-minded and superstitious in all ages. A clear understanding of Hypnotism, Mesmerism, Telepathy, Odylic Force, Psychological Phenomena, Clairvoyance, Black Art, and Spiritism, will throw light on many of these supposed supernatural mysteries. Under whatever name demonstrations may be known, they are all various phases of certain well-established laws touching our physical, mental, and psychical being. One of the most common, and best understood, of these mystery workings is Hypnotism which, defined, is "an artificial trance, or an artificially induced state, in which the mind becomes passive." The subject, however, acts readily upon suggestion or direction; and upon regaining normal consciousness, retains little or no recollection of the actions or ideas dominant during this condition. Hypnotism is purely mental and physical; but this strange power which one can exercise over another strikingly illustrates the influence which Satan exercises over millions of blinded subjects. We shall avoid any attempt to discuss the science and philosophy of Hypnotism; this phase of the subject is not germane to our discussion. All these subtle laws of mind, acting in relation to the body, only now being understood by scholars, are undoubtedly familiar to our common Enemy. We believe that centuries before man knew anything about psychic laws, as understood to-day, strange, unaccountable influences were operating on the wills and consciences of men. Hypnotism is a form of sleep; but during the time the subject can receive and obey instructions. They are absolutely under the control of the hypnotist. Paul caught an extraordinary vision of sin when he exclaimed to the Ephesians: "Awake thou that sleepest, and arise from the dead." Here is a fearful figure of sin: that it is sleep--semi-consciousness-- unconsciousness; yet they think, act, move about, enjoy, love, hate, etc., etc., and they are as one asleep. Observe this state is, if allowed to remain _in articulo mortis_, Hypnotism, conducted by the Master of Black Art; and they obey his will, over against observation, warning, wisdom, experience of others, even of themselves. Voices may call loud and long, but do not awaken the soul under the satanic spell.
