Scientists believe that man’s whole body consists of visible physical body & invisible energy body, also known as Bioplasmic Body. According to the law of correspondence what affects the physical body affects the energy body and vice versa.
When we have medicine, it releases certain chemical compounds which act on cells & carry out body’s metabolism.
However, in Pranic healing the energy is transferred in the form of light energy which is invisible to naked eyes but when this energy is absorbed by the cells it is transformed into chemical energy and then cells themselves carry out the normal metabolism.
