Nadi Astrology is also termed as "nadii jyotisa" which is a form of Dharma astrology followed in diverse zones in India. It is being considered on the faith that the past, present and the future lives of all human beings were predicted by Dharma sages in old-age times.
Nadi Astrology (Nadi jyothidam) is a form of Dharma astrology practiced in Tamil Nadu, Kerala and adjacent regions in India. Basically, the Nadi palm leaves are located based on the thumb impressions (right for men, left for women). There are 150 Nadi's in a sign; each sign is 30 degrees of the zodiac 360. Twelve signs of zodiac are grouped into three categories: Movable (Chara), Fixed (Sthira) and Dual (Dvisvabhava) signs. The phraseology of 150 Nadis is distinctive to each of these three types of signs. There are 1,800 Nadis in 360 degrees. Numbers and names of Nadi's are similar among all four Chara signs. Among all four Sthira signs, numbers and names of Nadis are alike, but numbering is peculiar from those in Chara and Dvisvabhava signs. Further, numbering of Nadi's in all four Dvisvabhava signs are similar among themselves, but different from Chara or Sthira signs.
