Archetypes are not as mystical and esoteric as people think. To use a computer metaphor, archetypes are essentially like the software of the psyche. But we can't get them mixed up. If we need to go to battle, or conquer something, or achieve a goal, the Warrior can help us do this. It is like a pocket of energy with a narrative structure that can help us gain courage.
Archetypes are patterns in the psyche that everyone has.
Anyone from any culture in any time has access to them. They are inner resources or helpers that we can call upon on our quest. They are deeply embedded within us. Some of them find us. Very often we don't even know we have an archetype, we're just going around acting a certain way and seeing the world out of a certain lens.
