Astrology is followed differently in different areas of the world. The significance of Naadi Astrology followed in Tamilnadu is that it is pretty sure to give accurate prediction. Again it is believed that unless Lord Siva wills no one can come to Naadi Astrology to know the prediction. Among all, 'Naadi Shastra' gives the most accurate results. Why? Because it is predefined and pre-documented by the Rishis as utterances of Lord Shiva himself. As the Lord Shiva has predetermined the course of your life, so will it be -- and you may be chosen to know about the occurrences before they happen. Naadi Astrology, like other predictive sciences, runs on the dictum that the fate of every human mortal is predestined. Naadi also prescribes penances and remedies based on one's past deeds or karmas. However, the unique and fascinating belief -- that only a person who has been destined to know his fate will approach the Naadi reader at a 'predestined age' and at a 'predestined' time -- makes it different from other occult sciences.
