You do not need to be thinking all the time dur ing your waking hours. Such habit Of mind soon exhausts, and keeps you putting out the same set Of thoughts, a train Of idea over and over again. One Of the greatest sources Of power and health, both Of mind and body, is the ability to dismiss all positive thought at will, to sit perfectly quiet physi cally, to pass, if but for a few seconds, into a dreamy state or reverie; to see only the landscape that may be before the physical eye, or even but a' very small part Of that, or to allow the mind to divell and live in such mental pictures as may come to it.
