There is probably no other question that would cause so many false, controversial, less often correct, opinions than hypnosis. And there are still conflicting views on hypnosis. Hypnosis has been known to mankind since time immemorial. But for many centuries it was shrouded in a fog of mysticism and religion. Priests and magicians, "predictors" and "miracle workers" used hypnosis to deceive the people. And now in a number of capitalist countries they show with the help of hypnosis "miracles of clairvoyance" and "healing" in order to strengthen faith in gods and otherworldly forces. However, the pervasive light of knowledge has reached this complex, previously supernatural phenomenon of nature. In the works of the great physiologist I.P. Pavlov and his students scientifically explain the properties of hypnosis. Scientists have discovered the nature of hypnosis and put it in the service of medicine. They proved that correctly and skillfully used hypnosis and suggestion are powerful weapons in the fight against various diseases. So hypnosis became a friend and healer of people. How did humanity get acquainted with hypnosis? How in the past and now religion is trying to use hypnosis? How did the science of hypnosis explain and began to apply it in the treatment of diseases? All this is described in the brochure of the doctor of medical sciences V.E. Rozhnova and M.A. Rozhnova "Hypnosis and religion."
