With time, the leaves got scattered and they were collected and categorized during the chola rule in Tanjore and preserved in the Saraswati Mahal. The leaves got destroyed and burnt during the Muslim invasion and in the British regime, they gave away the nadi leaves to some families and some were sold and auctioned. They kept in possession only those that revealed knowledge of herbs, alchemy and medicines. The nadi leaves were sought by astrologers from a community called Valluvar and they belonged to Vaitheeshwaran Koil, near Chidambaram in Tamilnadu. Vaitheeswaran Koil became the heart center for nadi astrology.

The astrologers made their living through nadi predictions, who got trained at reading them from their elders and this was passed down from generations to generations. Around 13th century, Some nadi leaves that were lying scattered in Vaitheeswaran Koil were collected and preserved under Maratha ruler, King Serfoji. He was a true patron of arts and sciences who stored these nadi leaves in the famous Saraswati Mahal at Tanjore. But currently, Vaitheeswaran koil is the main place for nadi astrology. Many Brahmin communities practicing astrology have come in possession of nadi leaf bundles and some are sent to other parts of India too from this place. Shiva nadi jyotisha is the most popular among nadi astrology predictions.

Predictions are made taking the thumb impressions of an individual and it is said that there are 108 types of thumb impressions on this earth. The leaves are found across India, Sri Lanka, Tibet, Nepal and they are written not only for those of Indian origin but for souls across the world seeking relief from this bondage of suffering and pain. The leaves are written for a few and if destined, one would certainly seek the leaf for a new turn of life.

The Maharajah Serfoji II of Tanjore, who was a great patron of the arts & sciences, stored these leaves in his palace library so they would be available for the future. The British retrieved these leaves during their kingdom and later sold them to some Indian families, who still keep them. These families carefully maintain them and continue to train people in the proper reading the leaves so that people may still benefit from the ancient advice of these Siddhas as well known as Naadi Family. Now these Siddhas consider being Nadi family. The Nadi reader Mr.Velmurugan practices nadi astrology in this area around Vaitheeswaran koil and belong to one among the best nadi family.

Around the 12th century, these leaves were found lying in the location of South India ancient Vaitheeswaran Koil in Tamil Nadu. The Nayanar community which found these leaves realized their values &made exact copies of them and have been the custodians of the Nadi Leaves since then. They are also the only community which have been for generations trained to read the leaves, and interpret them to make the predictions. Also they are the only people who have access to the Nadi leaves and still following this one of traditional Nadi astrology. Later astrologers who were very much interested in knowledge related to Nadi astrology they got the leaves from the library. It seems that these palm leaves were originally written on animal skins &some leaves later texts were copied on palm leaves. These sources were also maintained by applying oil extracted from peacock's blood. The primary Centre for Nadi astrology is located in Vaitheeswaran koil in South India.
