This shows that sleep is a form of repose, automatically brought about, which lifts us up from anxieties, worries, and discomforts, from sorrows and troubles. When this condition of repose can be brought about at will, one will have an experience of mastery, for then one is not dependent upon an automatic condition. If this condition which raises us above our worries, troubles, sorrows, anxieties, pains, and suffering can be produced within ourselves, a great thing is accomplished. And the way of accomplishing it is by the practice of repose.
