Analytical psychology (or Jungian psychology) is the school of psychology originating from the ideas of Swiss psychiatrist Carl Jung. His theoretical orientation has been advanced by his students and other thinkers who followed in his tradition. Though they share similarities, analytical psychology is distinct from the psychoanalysis of Sigmund Freud. Its aim is wholeness through the integration of unconscious forces and motivations underlying human behavior. Depth psychology, including archetypal psychology, employs the model of the unconscious mind as the source of healing and development in an individual. Jung saw the psyche as mind, but also admits the mystery of soul, and used as empirical evidence the practice of an accumulative phenomenology around the significance of dreams, archetypes and mythology.
