The Self in Jungian psychology is a dynamic concept which has undergone numerous modifications since it was first conceptualised as one of the Jungian archetypes. Historically, the Self, according to Carl Jung, signifies the unification of consciousness and unconsciousness in a person, and representing the psyche as a whole. It is realized as the product of individuation, which in his view is the process of integrating various aspects of one's personality. For Jung, the Self is an encompassing whole which acts as a container. It could be symbolized by a circle, a square, or a mandala. Two center hypothesis The idea that there are two centers of the personality distinguished Jungian psychology at one time. The ego has been seen as the center of consciousness, whereas the Self is defined as the center of the total personality, which includes consciousness, the unconscious, and the ego; the Self is both the whole and the center. While the ego is a self-contained center of the circle contained within the whole, the Self can be understood as the greater circle. Emergence of the Self Jung considered that from birth every individual has an original sense of wholeness—of the Self—but that with development a separate ego-consciousness crystallizes out of the original feeling of unity. This process of ego-differentiation provides the task of the first half of one's life-course, though Jungians also saw psychic health as depending on a periodic return to the sense of Self, something facilitated by the use of myths, initiation ceremonies, and rites of passage. Return to the Self: individuation Once ego-differentiation had been more or less successfully achieved and the individual is somewhat anchored in the external world, Jung considered that a new task then arose for the second half of life - a return to, and conscious rediscovery of, the Self: individuation. Marie-Louise von Franz states that "The actual processes of individuation - the conscious coming-to-terms with one's own inner center (psychic nucleus) or Self - generally begins with a wounding of the personality". The ego reaches an impasse of one sort or another; and has to turn for help to what she termed "a sort of hidden regulating or directing tendency...[an] organizing center" in the personality: "Jung called this center the 'Self' and described it as the totality of the whole psyche, in order to distinguish it from the 'ego', which constitutes only a small part of the
