There are several different kinds of numerology; each has its particular strengths. AstroNumerology associates numbers with planets, which are astronomical bodies. AstroNumerology is not about adding numbers up; it is about looking at each individual number, since each represents a particular planet, and considering the totality of the number's own "planetary system." Each planet is further associated with different precious & semi-precious gems, colors, and the basic relationships of planets within the Solar System.
