The SUN
The Sun represents you as an individual, your identity, men in general, the father, the husband, your vitality, the honor of a man
It is also associated with self-esteem, self-confidence, conditions linked to your personality/yourself.
It is also energy, not like Mars which is energy you spend but like a power plant, your power plant providing you with life energy. Energy that sustain your life, like the Sun to Earth which is needed to sustain life on Earth.
It is associated with the House V.
The Sun is also the “spotlight”, your personal success.
Think of an artist on the stage of a theater, and the spotlight directed at her/him. She/He is in that very intense light circle, on stage performing, in the spotlight.
She/He is the one that everybody is looking at. This is her/his time.
That’s being under the spotlight, having some personal success.
