The stars and planets have always inspired a sense of wonder. Many cultures look skyward and see the face of the divine there. There's a cosmic dance on the grand scale, and one on the intimate scale, going on for each of us. Astrology is the study of patterns and relationships -- of planets in motion, our birth chart, synastry with others, the make-up of elements -- and using that knowledge as a tool to find meaning.

To produce a more accurate reading, astrologers check to see what sign each planet was in at the time of birth. The planets and signs combine with other elements, such as houses and angles, to form a complex and often very specific profile of a subject's personality, life and future prospects.

There is no single unified theory or practice of astrology. Ancient cultures all practiced their own forms, some of which combined and evolved into today's common western astrology. Eastern cultures continue to practice their own forms of astrology: Chinese, Vedic and Tibetan astrology are among the most well-known.
