Do constellations have anything to do with souls?

Yes, a person's sun and moon constellations are often the embodiment of the relationship between soul and self. The sun helps us establish our identity and supports it in concrete ways. The moon helps us feel happiness and pain, happiness and sadness, nourish and repair ourselves. The sun tells us who we are, and the moon describes the "affectionate" side of life. The function of each planet is further described by its constellation, which carries its own functions and affects everyone's every move.
