Nadi Astrology and Tamil Nadi Palm Leaf is a special branch of Vedic Astrology.
Nadi is 150th division of a zodiac house.
Recent research by eminent Astrologers had revealed that the ShodashVarga or 16 divisional charts of a horoscope, matches into the NadiAmsa or D-150.
D-1, D-2, D-3, D-4, D-7, D-9, D-10, D-12, D-16, D-20, D-24, D-27, D-30, D-40, D-45 and D-60 are ShodashVarga divisions.
Using simple divisional math the above divisional numbers gives a set of numbers as below with duplicates removed.
These numbers indicate the unique boundary of one or many divisional charts.
A total of the above such division for any house comes exactly to 150 parts, which is nothing but Nadi and its Amsa.
With this NadiAmsa, one can predict a person's current birth destiny from birth till death.
So be it Tathatsu.
