Astrology is an indicative science and no fatalism is implied. Past, present and future are imbedded in the womb of Almighty Time and Astrology is merely a diagnostic tool to understand the workings of Time Eternal. It is the application of the Law of Probability, based on astronomical facts. Cosmos, a grand clock with wheels within wheels clicks ceaselessly throughout our life journey and governs its patterns. A horoscope chart which we refer to very many times in our lives is just a small time slice of the vast cosmic performance.
The most widely practiced branch of Astrology is 'natal' astrology which analysis a person's total profile. By studying the planetary arrangements on your personal natal chart, astrology discovers specific information in order to help you direct your life with greater success. It provides the means of ordering and understanding your experiences, strengths as well as weaknesses.
Besides this another form of astrology that is practiced is "mundane astrology" i.e. the astrology of world affairs. This form of astrology examines the world events and charts of public figures. Then they determine how the future world would be owing to the occurrence of certain events and coming into limelight of certain public figures. One may ask "Why Mundane Astrology?" The answer is simple, because world affairs in one way or the other affect each of ours lives. This specialized field of astrology also deals with matters like weather, catastrophes, national and international affairs etc.
