Psychology of Mystical Consciousness

the long version

"The book offers the results of Albrecht's meticulous long-term empirical research into mystical consciousness. Albrecht's results from a pioneering methodological approach based on 'Autogenic Training,' which enabled a practitioner to verbalize spontaneously what he/she is experiencing while immersed in an altered state of consciousness. These spontaneous utterances of mystical (and non-mystical) experience were concurrently recorded by Albrecht and provided him with invaluable empirical data. The outcome was a most comprehensive, systematic, psychological phenomenology of mystical consciousness informed by long-term empirical research. Unlike other empirical studies in this field, which are either based on records of mystical experience retrieved retrospectively, derived from behaviorist research, or both, Albrecht's empirical data originate from immediate (not rationally mediated) verbal testimonies spoken by subjects while transported into a mystical state." -- Amazon.com.
