Nadi Astrology is an ancient Indian method of Astrology to learn about one's past, present and the future. Since 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.

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. Some of these palm leaf inscriptions available in Tamilnadu were standardized, ordered and classified in Tamil Nadu nearly 1000 years ago during the reign of the Cholas in South 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.

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.

History of Nadi Astrology

The origin of the nadi inscriptions can be traced back to approximately 2000 years ago. It is said that the ancient Indian Rishis or sages had written the life
patterns of each person on palm leaves by their Yogic Intuitive powers. These unique leaves were initially kept in the Saraswati Mahal library of Tanjore city (Thanjavur ) of Tamilnadu State in India.

Later during the British Rule, the British sold these leaves to the locals who very very much interested in getting them. People belonging to a particular sect called the Valluvar community of South India who specialized in astrology bought most of these leaves. Some of these were also acquired by the astrology families in Vaitheeswarankoil, a place near Chennai, the capital of Tamilnadu, a state of India.
The leaves were found lying idle in Vaitheeswarankoil aorund the 13th century. Some interested in Astrology realized their values and copied the contents on palm leaves and made exact replicas. These leaves have been handed down over generations to make predictions. They earned their livelihood through Nadi-Astrology. They got trained from their elders to do Nadi reading.
