Central to Jungian psychology is the concept of "individuation," the process whereby a person discovers and evolves his Self, as opposed to his ego. The ego is a persona, a mask created and demanded by everyday social interaction, and, as such, it constitutes the center of our conscious life, our understanding of ourselves through the eyes of others. The Self, on the other hand, is our true center, our awareness of ourselves without outside interference, and it is developed by bringing the conscious and unconscious parts of our minds into harmony.
