Body and Life
This body comprised of condensed gases, (which is called the material aspect), is not merely enough for life. There needs to be a constant revolution of particles, ethers and celestial gases (which are called spiritual aspects) within the body so that life can continue. In other words, the body by itself is not enough for life to continue. We need other forces of particles, like gases and astral, ethereal fields, to sustain life. They enter and exit the body through breathing, through the pores upon the skin, blood circulation, and through consuming foods and drinks. This notion is what is necessary for a person to continue living.
