Nadi Astrology is an ancient Indian method of Astrology to learn about one's past, present and the future. It is said that thousands of years ago, the great sages of Indian had the power to look into the past and future of the entire universe and recorded the life of each human being who either lived, were living or were to live. At some point of time, these discussions were written on palm leaves in an ancient Tamil script, which can now only be deciphered by expert Nadi astrologers.
However, it is quite unfortunate to note that no other form of astrology has been criticised or manipulated as much as Nadi Astrology. Nadi in Tamil means “ in search of“. Because one individual goes in search of his details in the nadi, this system came to be called by this name. The palm leaf inscriptions are scattered throughout India. There are Number of Nadis available named after the Rishis who composed the same. There are only a few Nadi readers available who could interpret the inscriptions which are written in the poetic language. There are various Nadis available like Agathiya Naadi, Suka Nadi, Brahma Nadi, Kausika Nadi etc.
Each Nadi is made up of a particular ola or palm leaf, written in Vatta Ezhuthu , a Tamil script, with a sharp, nail-like instrument called Ezhuthani. The palm leaves are preserved by rubbing peacock oil on auspicious occasions. These palm leaves are still preserved in the Saravasti Mahal library of Tanjore(Thanjavur), in the South Indian state of Tamil Nadu. The primary centre for Nadi Shastra is in Vaitheeswarankoil, near Chidambaram in Tamil Nadu, a state in South India.
There are twelve chapters (parts). The first chapter contains the native’s name, parents’ names, present details of profession, brothers, sisters, children, spouse and a gist of future predictions for all the twelve bhavas. There is also a poetic description of the planetary positions in the native’s horoscope. The other chapters deal elaborately every aspect of your life. For example, the fifth chapter deals with children, their birth, death, reasons for not having children, adoption, future- -life of the children, remedial measures etc. All these were written hundreds of years ago by our Maharishis.
The palm leaf inscription of an individual is spotted out by his thumb impression. Lines on the thumb of people on the earth are are classified into 108 types. The Nadi palm leaves are arranged according to these types. The Nadi readers identify the particular types of lines on the thumb and the corresponding set of palm leaves are taken.The time duration to pick up your leaf depends upon the identification of the thumb impression. Some impressions are identified easily and the corresponding leaves are found soon.

Leaves are there not only for Indians but also for foreigners and other nationals belonging to other religions and creeds. Destiny has leaves for those who wished to have their readings.It is also stated that about 40% of the people in the world only are likely to get these results as available.The other leaves might have been damaged or lost in the course of time.
