Sushruta Samhita describes 107 Marma points in the body. In Tamil traditions, 108 Marma points are enumerated and in Kalari tradition of Kerala 365 Marma points are in practice. Major marma points correspond to seven Chakras, or energy centers of the body, while minor points radiate out along the trunk and limbs. The points cover both the front and back of the body, including 22 on the lower extremities, 22 on the arms, 12 on the chest and stomach, 14 on the back, and 37 on the head and neck. (The mind is considered the 108th Marma.) Each has its own name based on their anatomical position. The human body needs Shodhana (revitalization) in order to perform its function normally and efficiently. In the Ayurvedic system, especially in Kerala, Marma massage is performed as a routine in preventive medicine. A professional therapist isolates Marma points and tones them by increasing blood flow to the affected part of the neuromuscular junction. They also aim to tone the surrounding muscles.
