Indian Astrology is in fact a science. But it is an inseparable aspect of Hinduism; every true Hindu has to accept Indian astrology. If he denies astrology and yet accepts Hinduism, he will be like one swearing on Bhagavad Gita and yet denouncing the concept of Chaturvarnya. Ancient Hindus have given us many sciences and Indian Astrology is one of them. In Hinduism the secular and the non-secular (religions) are the two sides of the same coin.

     Indian Astrology from the earliest times has been studied in India as a science with its ancestry in Hindu religion and Indian Astrology has a goal in spiritual realisation of Highest Reality.

     Indian Astrology has its roots in Indian Astronomy, which in its turn is imbedded in the Vedic culture and thought. Though the ancient people of the Vedic times observed many an astronomical phenomenon carefully, minutely and accurately, the compilation Indian Astrology has been handed over to Geometry and Physics. Indian Astrology was pre-occupied with discussions on the nature of Space, Time and Causality. For manifold reasons, the Upanishadic thinkers arrived at the formidable conclusion that Indian Astrology have an empirical validity and hence are relatively real.

     Indian Astrology was taken up by many sages like Parashara, Garga and Agastya. Parashara is the first system-builder in Indian Astrology. His Hora Sastra, though we now possess only a summary of it, is an epoch-making work. The allotment of the planets to the signs of the Zodiac has unique features in Indian Astrology. This is the first greatest contribution to Indian Astrology to the study of the planets in relation to the stars. This is the basis for all types of predictive astrology and for the development of Astronomy and physics as well.
