Vaitheeswaran temple located in Tamil Nadu is the nerve centre of Nadi Astrology. Like the nervous system that coordinates the various parts of the body, the Vaitheeswaran Temple regulates Nadi Astrology [palmblatt lesung] in such a way that all the predictions done by the Nadi astrologers till this day fall into correct place. The most famous town, as far as Nadi Jyothisham is concerned, is Vaitheeswaran Koil which is surrounded by many Nadi temples, with each temple having a remote past. As a brain centre of Nadi Jyotish, the town of Vaitheeswaran Koil reverberates with the ancient heritage and wisdom.The predictions of the future generations contained in the temples of the town are on Palm leaves and their guarantee to be authentic is expounded by Lord Shiva, from whose mouth the predictions have erupted only to be overheard by the saints or rishis of the ancient past, who wrote down them on the palm leaves for the reference of the future generations or by posterity.

Originally the predictions were written in Sanskrit by the great seers and sages of the ancient world like Bhrigu, Agastya, Kaushika, Vasishta and many others like them. The sages prove the truthfulness of the palm records and their growth during the various ages of development of the Vedas since the coming of Aryans and settling of them in India. It has to be noted that [palmblattbibliothek] Nadi Jyothisham is more popular in Southern India.

It was with the rule of Venkoji Maharaj that Maratha rule was established in southern India , and Tanjore emerged as the capital city. The control then passed over to the Britishers in 1798 in the hands of Robert Clive who was based at Madras Presidency. Marathas as the patrons of Arts and Sciences preserved the Nadi Shastra on Nadi Palm leaves at Tanjore Saraswathi Library. During the rule of the Britishers, the records were auctioned to the influential family and the control of Nadi Astrology [palmblattlesung] passed into their hands.

It was during the rule of Saraboji Maharaj that the Sanskrit palm leaves were translated into the poetic Tamil and were kept for reference by the future scholars in the Saraswathi library. It was the time of Mughal rule in the north India, yet the Marathas were able to safeguard the Palm leaves from any plunder by the Mughal rulers.Thus the Nadi Josiyam [palmblattlesung] owes gratitude to the Marathas for the survival of Nadi Shastra on Palm leaves today.
