Naadi is a Tamil word which means " in pursuit". Long  ago during the conversation between a Saint and disciple (MAHARISHIS) the disciple would ask  about a   particular human.The disciples question was answered by teacher  in the form of poems (TAMIL LITERATURE) which is full of predictions of present, past and future of the particular human being for whom disciple asked. The predictions has been written in palm leaves by the disciples of the original saint by around thousands of years ago. The palm leaves of divine words protected by his followers and is in use now in the world.

These predictions were inscribed on palm leaves. Like the many arts and science of the olden days these predictions were also in Sanskrit. However, A Chola King of South India, being a lover and patron of Science and Arts, later (about 1000 years before) gathered all the available palm leaves containing not only Naadi predictions, but write-ups on many other subjects, got them translated in Tamil (pertaining to most of the subjects) and stored all these leaves in big libraries in one of the palaces of the Kings called ,Saraswati Mahal", which is existent even today, in Tanjavur in Tamil Nadu

More than 300 years back, these palm leaves were auctioned during the British rule of India and were bought by some people in "Vaitheeswaran Koil", whose descendents are holding them even today. Vaitheeswearan Koil is in the district of Tanjavur which houses many beautiful temples built by the Chola Kings. One such famous temple is the "Brahatheeswarar Koil" These palm leaves namely Sri Kausika Mahasiva Naadi, containing predictions pertaining to many human beings, have been broadly grouped under 108 categories. Each category is identified with the "markings on the human thumb (left in the case of women and right in the case of men). Each category is named separately "Rettai Chuli Mahudam" (Double circled CrownThe thumb impression of a person is obtained and after ascertaining its classification, the well-trained reader is able to locate four or five bundles of leaves (each containing about anything between 25 to 100 leaves). They are all punched with two equi-distant holes in the centre and tied in between two quarter inch thick wooden frames (about 10 to 16 inches in length and one inch in width) The reader brings only one such bundle at a time and he reads for only one person. The reading for a person's introductory part takes anything between 30 minutes to one hour depending on the length of the life he is going to live.
