Transpersonal psychology is the study of human nature that begins with the
assumption that humans have potentials that go beyond the limits of their ego and
integrate spiritual experience into a broader understanding of the human psyche and
consciousness. Altered states of consciousness have been used as psychotherapy in
transpersonal to help individuals for self-exploration and self-analysis and proposed by
many psychologists during the last decades as a way to explore the human psyche and
provide a better understanding of the human mind.
