The theoretical foundation of Thai massage is based on the concept of invisible energy lines running through the body. 

The Indian origin and influence is obvious here since the background of this theory clearly lies in Yoga philosophy. Yoga philosophy states that life energy (called Prana) is absorbed with the air we breathe and with the food we eat. Along a network of energy lines, the Prana Nadis, the human being is then supplied with this vital energy. Out of these energy lines Thai massage has selected 10 main lines on which there are especially important acupressure points. Massaging these lines and points makes it possible to treat a whole range of diseases or to relieve pain. The 10 main lines are sufficient to conduct practical treatment for the whole body and its internal organs. Disturbances in the flow of energy result in an insufficient supply of Prana, which will in turn lead to sickness. Working on the energy lines with massage can break the blockades, stimulate the free flow of Prana, and help to restore general wellbeing.
