Perception of body is an essential exercise for acquiring not only physical goodness but psychical goodness also. It is an efficient tool both for healing and maintaining good health.
Modern scientific research has now established that there is no denying the fact that sick people do get well by harnessing the psychic forces through mental imagery. The body's natural defence mechanisms against infection, contagions, toxicity and other pathological disorders constitute the immune system of the body. Immunology, thus, means scientific study of body's defences and resistance to infection etc. It is essential to obtain some knowledge about our body.
