There are various nadis, palm leaf inscriptions available like Atrinadi, Jeevanadi, Grahanadi, Siva nadi, Duruvanadi, Edumbinadi, saptarishinadi, Nandhinadi, Bheemanadi, Nava nadi, Vashistanadi, Agasthiyanadi, Shukhanadi, Brahma nadi, Kaushik nadi, Vashistanadi. As we already mentioned above Nadi Astrology can be known in other names such as naadijosiyam, naadijyotish, nadijosiyam, nadijothidam.
The basic concept of Nadi Astrology is "Nadi”. There are 150 Nadis in a sign or Rashi, one sign is 30 degrees of zodiac.
Twelve signs of zodiac grouped into three Categories:
Movable (Chara), Fixed (Sthira) and Dual (Dvisvabhava) signs Nomenclature of 150 Nadis is peculiar to each of these three types of signs. There are 1800 Nadis in 360 degrees. Numbers and names of Nadis are identical among all four Chara signs. Among all four Sthira signs, Numbers and names of Nadis are identical, but numbering is different from those in Chara and Dvisvabhava signs. Similarly, numbering of Nadis in all four Dvisvabhava signs are identical among themselves, but different from Chara or Sthira signs. For instance, the first Nadi in Chara signs such as Aries is VasudhaNadi, but in Sthira sings the order is reversed and Vasudha is 150th Nadi. In Dvisvabhava signs such as Gemini, Vasudha is 76th Nādi, ie from the middle of 150. Thus, there are 450 distinctive names and numbers in full zodiac. Nadi texts use this concept of Nadi as the basic unit for prediction. That is why they are called "Nadigranthas".
According to the principles of Nadi Astrology the Zodiac is divided into 12 equal sub divisions of Signs with equal subdivisions of the 27 Nakshatra. These Nakshatra are further subdivided into unequal "Sub lords". Nadi Astrology lays greater emphasis on the sub lord which is stronger than the Nakshatra& in the same sequence the Nakshatra is stronger than the Planet.
Experience shows that the system of study of Astrology through the Sign, Nakshatra and Sub lord gives most accurate results because in this system we judge every planet on THREE platforms. In this system we cast the horoscope of the native by taking date, time and place of birth and draw the Lagan chart and NirayanaBhavaChalit chart. For predicting any event but combination of Houses is taken into consideration not like in other system of astrology where a single House is taken for giving predictions. For Timing each event Vimshottari Dasha is used with the final use of Transits.
These spiritual powers are etched deep inside our entire being and some very rare human beings, have the discerning powers to revoke this spiritual connection. Astrology defines that their is relation between astronomical phenomena and human world. Astrology comes from latin word "astrologia" which means study of - accounts of the stars and later passed into the meaning of star divination.
