Nadi astrology is the only predictive hindu system of astrology in which the Zodiac is divided into 12 equal sub divisions of Signs with furthur equal subdivisions of the 27 Nakshatras . These Nakshatras are further subdivided into unequal “Sub lords”. Nadi Astrology lays greater emphasis on the sub lord which is stronger than the Nakshatra & in the same sequence the Nakshatra is stronger than the Planet.
Experience shows that the system of study of Astrology through the Sign, Nakshatra & Sub lord gives most accurate results because every planet is judged on three platforms . In this system Lagna Chart and the Nirayana Bhava Chalit Chart is drawn by taking into consideration the date , time and place of birth of the client . For predicting each event not a Single House but combination of Houses is taken into account . For the Timing of each event , Vimshottari Dasha is used with Transits .
Prediction based on Sun Signs are not accurate as here we are dividing 700 crore people of the world in 12 signs , which means we are predicting same for 60 crore people of different age , cast , creed and religion whereas the fact is that even twins are different .
