The term "naadi astrology" is a very misleading way of describing the phenomena because they are not predicting anything there. They are actually stating with accuracy a person's life - the past, present and the future. That is why anyone who is destined to get it read to them, comes out shocked and shaken after the reading.
That is one of the reasons why I used the term "Naadi Divination" in my article. However many people continue using the term "Naadi Astrology" and contribute to the confusion and the attendant muddled discussion.
As for natural phenomena and national issues, I am not aware of "naadi divination" dealing with such matters.
Thank you very much for dropping by. Much appreciated.
