The Siddhar in Tamil tradition is a perfected individual, who has attained spiritual powers called siddhi. Historically, Siddhar also refers to the people who were early age wandering adepts that dominated ancient Tamil teaching and philosophy. They were knowledgeable in science, technology, astronomy, literature, fine arts, music, drama, dance, and provided solutions to common people in their illness and advice for their future. Some of their ideologies are considered to have originated during the First Sangam period.
Practice
Typically Siddhars were first Scientists, saints, doctors, alchemists, and mystics all in one. They wrote their findings in the form of poems in the Tamil language, on palm leaves which are collected and stored in what is known as the "Palm leaf manuscripts". These are still owned by some families in Tamil Nadu and handed down through the generations, as well as being kept in public institutions such as universities in India, Germany, Great Britain, and the United States. In this way, Siddhars developed, among other branches of a vast knowledge-system, what is now known as Siddha medicine, practiced mainly in Tamil Nadu as a type of traditional native medicine. A rustic form of healing that is similar to Siddha medicine has since been practiced by experienced elders in the villages of Tamil Nadu. "Naattu marunthu and Mooligai marutthuvam'' ). Siddhars are also believed to be the founders of Varmam - a martial art for self-defense and medical treatment at the same time. Varmam are specific points located in the human body which when pressed in different ways can give various results, such as disabling an attacker in self-defense, or balancing a physical condition as an easy first-aid medical treatment. Tamil Siddhars were the first to develop pulse-reading to identify the origin of diseases. Siddhars have also written many religious poems. It is believed that most of them have lived for ages, in a mystic mountain called Sathuragiri, near Thanipparai village in Tamil Nadu.
