Brihat Parasara Hora Sastra is an ancient text dealing in Indian astrology. This ancient text has been composed by a revered sage named Parasara, around 3000 BC. It describes the various principles and guidelines to be followed in astrology. These principles form the foundation of the Indian astrological system, which is renowned the world over as Vedic Astrology
The Brihat Parasara Hora Sastra mentions the nine planets in the solar system and their effects in human life. According to Sage Parasara, these nine planets are actually the incarnations of god. Through these heavenly bodies the lord decides the fate of a person by calculating his/her ‘karma (deeds).
The knowledge imparted by Brihat Parasara Hora Sastra was passed on by Sage Parasara to his disciple Maitreya. The essence of the great scripture was thus handed down through various generations. In the due course it inspired other sages to write their own versions of astrology based on the book. All these later texts however follow the guidelines prescribed by Sage Parasara.
