Transpersonal psychology is the study of human nature and rests on the assumption that human beings possess potentials that exceed the limits of their ego and integrate the spiritual experience within a broader understanding of the human psyche and consciousness. Altered states of consciousness have been used to aid psychotherapy by transpersonalists for decades. Although there are very well-known techniques to induce altered state of consciousness such as holotropic breathwork, the book proposes other techniques including channeling and neurotechnology. Channeling is a parapsychological phenomenon which is considered an altered state of consciousness, although there are many differences of opinion as to whether channeling is really true or not, what is known is that in many cases is that this phenomenon can be attributed to the psyche of the individual who manifested channeling and could be used in psychology to know more about the inner subconscious of the individual. Neurotechnology offers an alternative way not only to induce these states for transpersonal therapy but also to measure the level of a state of consciousness with the use of quantum biofeedback.
