A human body requires Dasavayus (10 vayus) namely Pranan, Abanan, Viyanan, Udanan, Samanan, Nagan, Koorman, Kirukaran, Dananjayan, Devadathan, for its proper functioning each vayu has its own function to keep the body healthy and disease free. Among all these Pranan or Pranavayu is the most important one. Pranavayu controls the function of all other vayus. It flows across the six atharas, the three dasanadis (Idakalai, Pngalai, Sulumunai) from vertex to sole. The entire path of the pranavayu consists of junctions or places where it stays temporarily. These junctions are called Varmam. There are 108 Varmam or Varma points in our body. Out of these 12 are Paduvarmam or the Varmams which when injured can lead to death. The other 96 are Thoduvarmam which are used in therapeutic purposes.
When the body gets injured on a particular part due to some trauma leading to shock or fracture, the pranan changes its path and gets scattered from its original place to any other area. During this time the person may experience excruciating pain which may also refer to other area leading to syncope, and even coma. These sorts of injury if not treated in a specific time period may lead to deadly or fatal conditions. The signs and symptoms which the patient shows due to such trauma may mimic different other diseases and misguide the physician from the correct diagnosis. Such conditions can only be understood and treated by a honest, truthful, believer of God, Guru (The teacher), experienced Asan or a Marmani. The Asan, with his different therapeutic techniques and prayers can treat any Varma injury completely. They are noble people who serve the mankind without seeing their personal interest or in need of money.
