Astrology is not a complex science as it often made out to be and, in the hands of the world-famous "human computer" Shakuntala Devi, it becomes yet simpler and easier to understand and practise. The present book discusses zodiacs, planets, asterisms, the rising signs, Bhavas, Yogas, Dasas and their effects and transits. It enables the reader to cast a horoscope, and also read one. There are tables of correction for various cities and for sidereal time. It is a complete book that leaves nothing to become an amateur astrologer.
