Varma Kalai, also known as Marma Adi, is one of the oldest and deadliest forms of martial art in history developed in South Indian region, more precisely from Tamil Nadu. The tamil word “Varma Kalai” literally means “The Art of Vital Points”. Varma Kalai uses pressure and precise strikes to vulnerable pressure points on the human body to heal, maim or even kill someone depending on what part of the body is hit and how much pressure is applied based on periodic energy flows (time-dependent) streaming through the body along meridians
This is still exists in Kanyakumari district of Tamil Nadu and is called the southern style of kalarippayattu. Its a unique Neuro Martial Art in warfare practised by the Royal Thiruppad Nadans to defeat/kill the enemy without any external injuries are called Varmam. Varma Kalai is the master of all arts, royal to its name, practised by Asaans ( masters). An Asaan of special rank is a master over 108 Kalaries. These Asaans were the real kingmakers and known as Gramavadins or Gramanis, a term applied to communities like Nadars and Devars. They were the very ancient rulers of South India. Varmam or Marmam When one is affected by Varmam, it stimulates or blocks one or more of the 10 Vayus (air) governing the life centers of the body, which in turn acts on the Sapta Dhathu (Seven Vitals) of the body namely Ninam, Kapham, Majjai, Suklam, Moothiram Pethi and Viyarvai (blood, lipid, marrow, semen, urine, stools, sweat) respectively, and makes the desired effect to the enemy and causes his death or unconsciousness. Sidha Grandhas This Art is the one mentioned in the 300000 Grandhas (Books) of the early Sidhas. More than 75% of the original Sastras have been either lost, sold out or destroyed due to negligence and also through the over conservative character of the people who handled this Art. Yet, there are sufficient quantity of these rare Grandhas, in the form of Palm-Leaf Texts in Southern India. The Asaans of Kanyakumari, Kollam and Trivandrum Districts, although getting weaker at present, are still alive to the standard of these rare records. In order to learn this Art, it was necessary to work with an Asaan for a minimum period of 12 years in those days. This Art was not taught to anyone who came forward.
