The Zia Symbol is a sacred symbol that originated from the Zia Pueblo here in New Mexico. Each group of rays has a very specific meaning - to the North the rays represent the four cardinal directions, to the West the rays represent the four seasons, the the South the rays represent the four mountains of life (infancy, adolescence, adulthood, and becoming an elder), and finally to the East the rays represent the four aspects of self - heart, body, soul, and mind. The circle in the center binds all of these together. The Sun is considered to be the father of the Zia people, and the Earth their mother.
The Zia is also the New Mexico state symbol.
