**Abstract**

The chapter describes the author's integrative theory of hypnosis and hypnotherapy (ITHH) and the universal hypnotherapy (UH) method. The ITHH contains neurophysiological, biological, and communicative components. (1) Hypnosis is triggered by symbolical hypnogenic situations of inability of decision-making and/or its behavioral realization. Hypnosis development results in qualitative reorganization of the brain activation system functioning from distribution to generation of activity. Hypnosis deepening is based on the increase of brain activation. Hypnosis development in right-handers is associated with a regressive reorganization of the left hemisphere to the right hemisphere functioning mode, with whole brain functioning on right hemispheric principle. (2) Hypnotization generates hypnogenic stress. Hypnotherapy activates a readaptation process, including neurohormonal, neurotransmitter secretions; activation of the immunological and biochemical responses; and spontaneous change of pain sensation. (3) Hypnotic communication styles (directive, non-directive) are (i) changing due to historical evolution of social communication styles and (ii) indirectly using the representations about hypnosis. The UH utilizes the ITHH, being close to the positive and mindfulness psychotherapeutic approaches. The complex of UH and psycho-education formed positive-dialogue psychotherapy (PDP) for the treatment of anxiety disorders. The randomized clinical trial of PDP efficiency in the therapy of panic and generalized anxiety disorders confirmed high clinical efficiency and the mindfulness effect of UH.
