Marma is a Sanskrit word meaning hidden, or secret. By definition, a marma point is a juncture on the body where two or more types of tissue meet, such as muscles, veins, ligaments, bones or joints. Yet marma points are much more than a casual connection of tissue and fluids; they are intersections of the vital life force and prana, or breath.
According to Siddha system, marma is nothing but blockage of vital energy (Vasi) in the body. This blockage could be due to external physical injuries, psychological passions or imbalance of tridoshas. This effect can be felt at the psychic energy as marmas can be controlled by psychic powers. . This is used for enhancing the psychological powers by the use of mantras as well as by yoga also.
