The Nadis (Pranic Energy Channels) contain special points, that is, acupressure points or acupoints, which in Ayurveda and Yoga are called Marma points. By the way, in the south of India, in the Indian Tamil Nadu state, they are called Varma points.
Marma points are the “doors” or “windows” where Pranic energy that runs through the Nadis enters the physical body. In fact, they are seen as junction points in/on the body that connect energy and matter (or mind and body, if you wish).
Each Marma point has different effects on various parts of the body and corresponds to specific functions and bodily tissues. Seven special Marma points (the so-called Mahamarmas or Great Marmas) have major significance and correspond to the seven Chakras.
It’s thought that the knowledge of Marma points came into existence because of Indian martial arts warriors in ancient times who used special points (or Bindu) to disable or kill enemy fighters or, by contrast, to heal or speedup recovery from injuries.
Generally, 107 or 108 main Marma points are recognized, and they can be manipulated with, for instance, acupressure, stretches, herbal medicine, massage (such as Ayurvedic Marma Chikitsa) and Yogic exercises to cure or alleviate specific physical, mental, emotional and spiritual illnesses or discomforts.
