A unique system of analysis based on zonal effect of rasis and planets posited therein and influenced by other planets from specified places is the main principle of Bhrigu Nandi Nadi expounded by R.G.Rao of Bangalore. Based on his works earlier book “Prediction Secrets- Naadi Astrology” was published. In the process of experimentation with the combination of the planets it was found that every birth has a set-pattern of planetary positions. The matrix formed at macro level indicates the purpose of the birth. At micro level with zonal and star influences detailed study of nativity will reveal many secrets. The star level needs to be explored with details of stars from the sacred texts. But the place of birth having different Year Lords, Month Lord the Day Lord, Hora Lord and Sub Hora Lord have equal influence in differentiating nativities. In this book an effort is made to identify the matrix at macro level for certain births. A deep analysis with the aid of Hora Lords etc. will definitely give the purpose of birth. Even with little efforts we can go to previous births. The horoscope of yogis are dealt with reference to Sub Hora Lords. There is also an example of analysing horoscopes having similar planetary combinations. This is a beginning of research in Naadi Astrology and the days are not far to reach the truth behind the Celestial Matrix influenced by subtle bodies. This is a handbook on Naadi System for the students and astrologers to develop further in the subject.
