The Sun is the center of our solar system and the gravitational anchor of the astrological chart. It represents the "I Am," the conscious ego, and the will to exist. It is the hero of the personal myth, the protagonist of the life story, and the source of all vitality.
The Sun governs the essential self - the part of the psyche that filters experience and makes decisions. It is the engine of the personality, dictating conscious purpose and the drive for self-actualization. It represents the father figure, the king, the leader, and the creative impulse that seeks to leave a mark on the world.
The luminaries represent the core polarities of consciousness - the conscious self and the subconscious.
When solar energy is healthy, the individual exhibits confidence, warmth, generosity, and strong leadership. They radiate energy that uplifts others with a sunny, optimistic disposition. There is a sense of purpose, dignity, and natural ability to organize and inspire - the benevolent King archetype.

In Greek tradition, the Sun is associated with Helios, the Titan who drove the chariot of the sun across the sky, seeing all deeds. The deeper psychological archetype is Apollo, god of light, prophecy, music, and healing - the civilized solar force bringing order to chaos.
