 Jung provides some case studies to illustrate his ‘technique of differentiation between the ego and the figures of the unconscious’ and encourages the active production of fantasy imagery in his patients as a way of integrating the unconscious.Jung describes how integrating the anima with the ego fills the ego with a sort of magical knowledge (mana), and this state of ego inflation is described as possession by the archetype of the magician (the mana personality).Jung advises cultivating a second, superordinate center of personality, away from the ego yet not completely unconscious, which Jung calls the Self, as a container for this psychic energy from the unconscious.
