Rh ited, so that ordinary sensations of sound, touch, etc., cannot reach the brain. But because this inhibition is not complete, a sufficiently strong stimulus from without restores this electrical conductivity and is reported to the brain, awakening the person. Yet always in sleep there is a steady electrical flow into the internal organs,—heart, lungs, etc.,—so that they keep on throbbing and working.

As the control of life electricity in sleep is not complete, bodily sensations of discomfort, disease, or strong outside stimuli disturb it. But through a scientific process of control, which is not here described in detail, we can simultaneously control the external and internal organs of the system in a perfect way. That is the ultimate result of practice. But it will take long, long years to attain that perfect control. As after sleep, which is rest, the outer organs are invigorated, so the internal organs, after rest, as a result of the practice of this scientific method, are
