Our many life functions are controlled by this energy. Now it is a proven fact that a person lives with this energy and stores all his feelings in this energy field. This storage of his feelings affects the working and all the physical functions of his life. This energy field consists of three bodies that completely constitute our whole body, i.e. the physical body, energy body and the mental body. All the bodies have different functions of life.
Physical body takes care of the physical functions.
Energy body collects energy from universe and flows it into the body. Mental body controls the thoughts. As mental body controls our thought process, on analysis we find the fact that whatever we think goes into the mental body and our working gets affected accordingly. If we think negative then negative things happen in our life and we keep on doing this process life long. Secondly if we study the principles of energy we find that energy always flows from higher level to lower level.
