We have a conscious mind and an unconscious mind. The ego is the center of the conscious mind. On the surface of the ego, is the persona or social mask of the ego. This is how you present yourself to world and to strangers. The persons contains your style, attitude, quirks, etc.. The ego can mold the persona based on will and choice and one's means.
Below the ego is the personal unconscious. This contains all your lifetime of memories and experiences, habits. It is like the hard drive of the ego connected to the learning and experiences of the ego. The ego proper, as the center of the conscious mind, is more like a private zone; I think therefore I am, that contains things that one may only share with family and close friends, as well as things only the ego may know and it may or may not wish to share.
Below the ego and the personal unconscious is what is called the shadow. This is the fuzzy interface between the personal and collective unconscious where personal and subliminal meet. The shadow is analogous to the shadow that is cast by the sun and follows the ego around. The sun in this symbolizes the inner self. The shadow often is not fully conscience to the ego, due to its depth, but is more often it is something others can see in each other, but not always in themselves. It is below the threshold of the ego and the conscious mind but can be made conscious with some practice. The weak person at time, can becomes strong since the shadow will fill in the gaps. They may not notice this but other people sense being out of place based on the ego and persona.
As we go deeper below the shadow, we enter the collective unconscious. The collective unconscious is composed of genetic based jukebox of archetypes or masks of the inner self. These are natural personality firmware based on our human DNA. This instinctive nature is at the lowest level, just below the shadow. In dreams may show up as an helpful or harmful animal.
The next level of archetypes is connected to archetypes of relationships. This is rooted on human relationship, but there are also connected to how things relative to each other such as social hierarchy, an empirical view of the universe and Santa Claus with a red suit. This is how things go together often by tradition more than logic. Something like Astrology show the planet relate to time of birth helping the ego to differentiate itself by how it relative to the universe. In a male this level is call the anima and in a female it is called the animus. It has cross sexual connection. The sailor calls the ship or the sea; she, which is a historical projection of the anima. In a dream she may be a girl or princess depending who deep within the firmware you go.
The deepest level are archetypes of archetypes of meaning. Whereas the middle level if about relationships that may be based on long standing traditions and are followed collectively by each culture, archetypes of meaning is more like the universal logic and wisdom of how why things are as they are. This goes beyond the traditions of any one culture, to collective human wisdom and shared knowledge such as science.
Below that is the inner self, which is rarely seen without wearing one of the archetypes. It may appear in dreams as unity symbols; 3-D ball, gold, clear crystal, the treasure of the dragon.
The one additional feature that is sort of cultural and ego centric addendum to the archetypes, is connected to learned knowledge of good and evil. Since most will be required to learn good and evil; law, so they can go good and avoid evil, the evil is repressed causing polarization is be set up between the conscious and unconscious mind; shadow or ID, that adds an dark mask to otherwise neutral naturearchetypes. I call it the Satan Subroutine. It sort of causes the natural neural Archetype to polarize. In terms of the archetype of meaning the polarization may show up in a dream a good and evil wizard. Or it can be a helpful or scary animal.
