Self-realization is a term used in western psychology, philosophy, and spirituality; and in eastern Indian religions. In the western understanding, it is the "fulfillment by oneself of the possibilities of one's character or personality" (see also self-actualization). In the Indian understanding, self-realization is liberating knowledge of the true Self, either as the permanent undying Purusha or witness-consciousness, which is atman (essence), or as the absence (sunyata) of such a permanent Self. Merriam Webster's dictionary defines self-realization as: Fulfillment by oneself of the possibilities of one's character or personality. In the Western world "self-realization" has gained great popularity. Influential in this popularity were psycho-analysis, humanistic psychology, the growing acquaintance with Eastern religions, and the growing popularity of Western esotericism. Though Sigmund Freud was skeptical of religion and esotericism, his theories have had a lasting influence on Western thought and self-understanding. His notion of repressed memories, though based on assumptions that some later thinkers have questioned, has become part of mainstream thought. Freud's ideas were further developed by his students and neo-psychoanalysts. Carl Jung, Erik Erikson, Karen Horney and Donald Winnicott have been especially important in the Western understanding of the self, though alternative theories have also been developed by others. Jung developed the notion of individuation, the lifelong process in which the center of psychological life shifts from the ego to the self. Erikson described human development throughout one's lifespan in his theory of psychosocial development. Winnicott developed the notion of the true self, while Horney had two views of our self: the "real self" and the "ideal self". Gerda Boyesen, the founder of biodynamic psychology, developed her salutogenic view on the primary personality and the secondary personality. Roberto Assagioli developed his approach of psychosynthesis, an original approach to psychology.
