Five Layers

         In our bodies there are five main layers; (1) Solid; (2) Liquid; (3) Heat; (4) Air and (5) Spirit-the energy-as follows; (1) Solid is the physical structure of cells, molecules and atoms systematically arranged in rows; (2) Liquid is the blood and other fluids circulating throughout the body; (3) Heat is the electro-magnetic waves which maintain temperature and all other chemical qualities; (4) Air is the oxygen and other kinds of gas which move everything rhythmically in all parts of the body; and (5) Spirit is the energy-particles which are otherwise called the life-force, astral body or ethereal body. The fifth layer, Energy, is the life-force, which is a group of millions and millions of tiny particles conjointly functioning within the body.
