Autogenic Training was invented by Johannes Heinrich Schultz as a method of “Self-relaxing concentration”, as he says in the subtitle of his 1932 book. His disciple Wolfgang Luthe described in 1961 the “neutralization effect” as one of the principal therapeutic mechanisms of Autogenic Training, proposed the new name of Autogenic Therapy and created ICAT, the International Committee for Autogenic Therapy, that promotes and oversees the teaching, research and applications of Autogenics. Professional training in autogenics progresses through three successive levels (trainers, therapists and psychotherapists), each with its own requirements and areas of application. In the last years the method has developed into a full-fledged psychotherapy, defined by scientific theories of human functioning and behaviour in health and illness, psychological and psychosomatic disorders and therapeutic mechanisms, a scope of therapeutic methodologies and precise techniques for training brain mechanisms to induce amplified states of consciousness (ASCI Therapy). The regular induction of the autogenic state enhances physiological self´-regulation, self-awareness and neutralization of traumatic and incoherent mental processes. The basic principles of autogenics, autogenicity, ASCI, neutralization, ideoplasia, education & training and dual concentration are discussed.
