Ancient universities of India did systematic and deep study of astrology. Indian scholars studied planets and their movements, constellations and other celestial objects in several mathematical calculations. Based on these calculations they made remarkable progress in the field of astrology. They also used to make several predictions by studying the movement of planets. One of the greatest astrologers and astonomers Varahmihir divided astrology into three sections namely Tantra’, ‘Hora’ and ‘Samhita’. He wrote a book called ‘Brihat Samhita’. This book gives information about effects of planets on man’s future, his characteristics, various classes of animals, the auspicious time of marriage, digging ponds and wells and making gardens.
