Astrology, in broad sense is a science that explains the impact of planets and stars (Nakshatras) on the life of human beings. In the sky, the planets move in a very dreadful speed and their speed creats magnetic power in the proportion to the speed of the earth .This magnetic power is responsible for the events occuring on earth.The emergence of human being is also a sort of an event, So all events viz. the birth, death, gains, loss, success, honour, profession, service, family, progeny are a concern of the planets and stars i.e. grahas and nakshatras.
Astrology is the study of the movements and relative positions of celestial objects as a means for divining information about human affairs and terrestrial events. Astrology has been dated to at least the 2nd millennium BCE, and has its roots in calendrical systems used to predict seasonal shifts and to interpret celestial seasonal shifts and to interpret celestial cycles as signs of divine communications.
