Lecture IX

During the day man is continually making use of his physical and etheric bodies. The life we lead from morning till evening exhausts these bodies, and what we feel as fatigue is nothing more than the expression of the fact that indirectly through the astral body all kinds of perceptions have been taking place in us as well as impulses of joy, of sorrow, and of pain; all these have been playing through us. This wears out our physical and etheric bodies, and in the evening we are tired because all day long we have been destroying them.
