In Hinduism, Agasthiya is a legendary Vedic sage or rishi. Some say that it was the sage Agasthiya who first brought and popularized the Vedic religion to south India. Agasthiya and his clan are also credited to have "authored" many mantras of the Rig Veda, the earliest and most revered Hindu scripture (in the sense of first having the mantras revealed in his mind by the Supreme Spirit Brahman.) In some reckonings, Agasthiya is also said to be one of the greatest Seven Sages or Saptarshis. The word is also written as Agasti.
Agasthiya was a great devotee of Lord Shiva. After Agasthiya reached the south, in answer to his prayer for revelation on the classical language of South India, Lord Shiva himself taught the classical Tamil language to Agasthiya. Agasthiya is said to have attended Tamil Sangam (convention) and staged his work, the Agattiyam or Agasthiyam. This is one of the earliest treatise on Tamil grammar. In the 2500-year old Tamil Sangam, Agasthiyakoodam has a history of being home of Siddha medicine and it is said to be the home of Agasthiya.
He is considered as the first and foremost person of Siddha. He is considered the guru of many other Siddhars. He is also called Kurumuni, meaning short (kuru) saint (muni). His contributions were to the field of Medicine (Siddha) and Astrology - especially Nadi Jodhidam(Jos(i)yam or Jothisyam). He is said to have lived for over 5000 years, and that one of his medicinal preparations, Boopathi Kuligai, is so powerful that it can even bring the dead back to life. Two of his students and disciples were Therayar and Tholkappiar.
The Lalitha sahasranama, which describes the 1000 names of the mother Goddess (Known commonly as Gowri, Parvati or Durga), was first revealed to the world when Hayagriva, a manifestation of Vishnu, taught the same to Agasthiya. Agasthiya is said to have composed the Aditya Hridayam, a hymn to Surya, and taught the same to Rama just before the war between Rama and Ravana.
Can you believe that someone in India is storing records of your entire life cycle ie, your past, present and future. Hard to believe but yes, this is called Nadi Astrology. Nadi is an ancient astrology, which has been composed by great Maharishis (sages) of India in the past using their spiritual powers. The sages recorded these predictions for every individual for the betterment of humanity and to safeguard dharma (righteousness). These sages predicted the characteristics, family history, as well as the careers of innumerable individuals contained in several thousand volumes, each containing around a hundred predictions. These Nadi prediction recordings, being the repository of wisdom of the Great Saint was one of the well preserved books for thousands of years by the many generations of rulers, until an auction during the British rule, when it finally became the proud possession of an influential family of Valluvar community at Vaitheeswarankoil in the Tanjore district of Tamilnadu.
The Rishis (sages), who dictated those Nadis, were gifted with such a remarkable foresight that they accurately foretold the entire future of all mankind. Many scholars in different parts of India have in their safekeeping several Granthas. Initially, Nadi Astrology predictions was thought to be just writing on Astrology, but soon it became evident that the scriptures contained some unique predictions of specific natives, who will come seeking them, at a particular stage of their lifetime, as foretold by the Great Saint in these predictions.
This great work makes us realize the limitations of human sciences. That great compilation predicting the future of all human beings born or yet to be born, eclipses the achievements of all other sciences put together. These predictive texts also contain a chapter recommending certain Pilgrimages or prayers, worship and charities at specific shrines, to neutralize ones past sins.
The origin of these palm leaves can be traced back to approximately 2000 years ago. It is presumed that the Sapta Rishis (Seven Sages) had written the life patterns of each person on palm leaves along with their types of names by their Yogic Powers. These unique leaves were kept in the Saraswati Mahal' library of Tanjore city of Tamilnadu State in India. Later during the British Rule the British were very keen to acquire these types of ancient leaves dealing with herbal cure, alchemy, fortune-telling etc; but left some of the astrological leaves to their loyalists. Some were put to auction also. People belonging to a particular sect called Valluvar community who specialized in astrology bought these leaves. Some of these were acquired by the astrology families in Vaitheeswarankoil about 60 years ago from Thanjavur Saraswati Mahal Library . The leaves were found lying idle in Vaitheeswarankoil during the 13th century. The forefathers found them, 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. Astrolologers earned their livelihood through Nadi Astrology. It is a hereditary profession for them. They received training from their elders to do Nadi readings. What is written on the leaves is read and explained by them. The language is poetic and the script is also different. It is the same as in the ancient temples. Some of the Nadis are available in the Oriental Manuscripts Library at Chennai, India though in mutilated condition and the Sapta RishiNadi was published in Tamil in six volumes lagna wise . The Sanskrit texts were translated and written on palmyra or palm leaves in ancient tamil language. There were some nadigranthas translated into another South Indian Telugu language. Marata King Sarabhoji and Chola Kings patronized this form of astrology and translations. It is stated that Sage Agasthya has written in Tamil.
For each thumbprint there will be 6 granthas (books). In each granthas there will be 108 sizes and 12 parts according to Siva Nadi and 50 sizes in Agastyanadi. This means for one thumbprint many stories of person can be read. In Siva Nadi more details are given as discussion between Lord Siva and Parvati than in Agastya Nadi . It seems that these Nadis were originally written on animal skins and some leaves and later they were copied on palm leaves. They were preserved by applying oil extracted from peacock's blood.
The Nadi readers say that natives whose leaves are there will someway come to them at the appropriate age specified on the leaves from any corner of the world. Leaves are there not only for Indian but for foreigners also belonging to other religions. Whoever desires to look into the leaves will go to them on their own accord. The word Nadi in Tamil means; (destined) to come own accord. Those who are not destined may not even know such a type of astrology exists. Even the very age when the native is destined to go to them is marked on the leaves. Whoever is destined to come will come. Faith is the root of their system. It is also stated that about 40% of the people in the world only are likely to get these results.
