What is PRANA or KI

Prana or ki is that vital energy or life force which keeps the body alive and healthy. In Greek, it is called pneuma, in Polynesian, rnana, The healer projects prana or vital energy or the breath of life to the patient; thereby, healing the patient. It is through this process that so called miraculous healing is accomplished.
Basically, there are three major sources of prana: solar prana, air prana, and ground prana. Solar prana is prana from sunlight. It invigorates the whole body and promotes good health. Solar prana can be obtained by exposure to sunlight or sunbathing and by drinking water that has been exposed to sunlight. Prolonged exposure or too much solar prana will harm the whole physical body since it is quite potent.
Prana contained in the air is called air prana or air vitality globule. Air prana is absorbed by the lungs through breathing and is also absorbed directly by the energy centers of the bioplasmic body. These energy centers are called chakras. More air prana can be absorbed by deep slow rhythmic breathing than by short shallow breathing. It can also be absorbed through the pores of the skin by people who have undergone certain training.
