Naadi astrology, an ancient system from southern India, especially Tamil Nadu, involves two distinct forms. The first type predicts an individual’s past, present, and future, focusing on aspects like love, income, and career. Jeeva Naadi, also known as Prasanna Naadi, is written on palm leaves in ancient Tamil and emphasizes Nakshatras and Gnana. Predictions in Naadi astrology are based on thumb impressions, with the right hand used for men and the left hand for women, reflecting the foresight of ancestral sages.
