ROLE OF MARMA

There are four basic purposes of Marma:

It remove  blocks in energy channels called shrotas.
It pacifies vata dosha, (air and space elements ), bringing it to its normal path— especially vyana vata, (a sub-dosha which controls the autonomic nervous system.)
It creates physical, mental and emotional flexibility.  Because of ama (toxins) and because of vata, human beings after 35 or 40 years of age become rigid — and this happens to animals and plants as well.  As vata increases in   body, it leads to degeneration.  This rigidity  means becoming fixed in ideas, emotions and physical movements.
This gentle treatment creates an opportunity to experience powerful and dynamic transformation at the physical, mental, emotional and spiritual level  by building a positive link with the unconscious mind.  Many a times, people are not able to go outside their ‘comfort zone’.  They think they have absolute limitations.  After Marma is done, they can start taking positive risks.

Marma Chikitsa is an important aspect of  Ayurvedic  treatment  where the application of pressure on these Marma points induces the flow of vital energy (prana) along a complex system of subtle channels called (nadis). Based on the knowledge enumerated in Dhanurveda ( dealing with knowledge of bow and arrow fights), 107 therapeutic Marma points are recognised by   Ayurveda. The injury to some of these lethal Marma points can lead to instant death. Massage is widely applied in the treatment of Marmas.
