According to the principles of Nadi Astrology the Zodiac is divided into 12 equal sub divisions of Signs with equal subdivisions of the 27 Nakshatras. These Nakshatras 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.
The experience shows that the system of study of Astrology through the Sign, Nakshatra & 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 & place of birth by drawing Lagan chart & Nirayana Bhava chalit chart. For predicting each event not a single House but combination of Houses is taken into consideration. For Timing each event Vimshottari Dasa is used with Transits.
Nadi astrology is only predictive hindu system of astrology. In traditional Hindu Astrology Parshari Astrology and Jamini Astrology are taught however these systems of astrology do not have any pin pointed method for predictions of events. Nadi Astrology deals with pin pointed predictions on all the events of life viz. Education, Litigation, Property, Vehicle Purchase, Travel, Career, Health, Marriage, Child Birth and Longevity. Nadi Astrology deals with these events of life in an exhaustive manner.
Nadi astrology is based on predictions that an ancient Tamil sage called Agathiyar is said to have written on palm leaves. The leaves were initially stored in the Saraswati Mahal Library in Tanjore, Tamil Nadu. However, most of them were auctioned during British rule. Families of astrologers from Vaitheeswaran Koil, a Shiva temple about 250 kilometers (155 miles) south of Chennai near Chidambaram, obtained the leaves and passed them down from generation to generation. Hence, Vaitheeswaran Koil is considered to be the birthplace of Nadi astrology.
Apparently, there's a palm leaf that corresponds to everyone. If you find your leaf, you'll get to know your future!
While Vaitheeswaran Koil in Tamil Nadu is regarded as the best place to consult a Nadi astrologer, the challenge is identifying the real ones from the fakes. Numerous people have reported not finding any legitimate astrologers there. They've either been told that Nadi astrology is a scam, or they've encountered scams from Nadi astrologers around the temple (such as this alarming must-read example).
Yet, the fact that many people can be seen getting rituals performed indicates some belief in it.
An ancient form of astrology practised in southern India, Nadi Astrology is based on the belief that the past, present and the future lives of all humans were foreseen and recorded on palm leaves by Hindu sages in ancient time.
A very ancient form of astrology, whose origins began in Southern India, Nadi Astrology is based on an old-age belief that the one can decipher the past, present and future of all humans through the text written on palm leaves. It is a popularly believed that the great Hindu sages of the yore foresaw the past, present and future of all humans and hence, recorded these on tree barks and palm leaves.
Nadi Astrology is practiced in the Tamil Nadu region as well as Kerala and other adjacent areas in South India.
