Personality and Psyche
The ego is apparently already born with the personality. It is the personality, as the personality consciously knows it. It is, in fact the core of the personality, drawing to itself a cohesive and rigid energy patterns from the subtler realms of the physical (etheric or quantum realm), emotional (or astral) and mental worlds.
A complex is an organized group or constellation of feelings, thoughts, perceptions and memories that exist in the personal unconscious, attracting to it or constellating various experiences. A person is born with a set of patterns in the personal unconscious, reflected in his deepest memories. However, as he interacts with the social environment, he accumulates experiences that add on the composite personal unconscious or release some complexes. The content of the personal unconscious is accessible to the ego.
Collective Unconscious and Persona
Archetypes are the structural components of the collective unconscious. An archetype is a universal thought form (idea) that contains a large element of emotion. It is a permanent deposit in the mind of an experience that has been constantly repeated for many generations.
In ordinary living, an individual may become so attached to the roles he plays to the point that he equate the persona with his ego. In experiencing setbacks with respect to any one role played in life, only then will the ego reflect and acknowledge that he is not his role, that there is indeed a distinction between the role and the actor of the play.
