Relaxation, if properly done, can relieve tension and fatigue more effectively in half an hour than many hours of indifferent sleep. It is an exercise of the mastery of conscious will over the body by the technique of autosuggestion. Will, however, is not the tyrant with dictatorial powers, cracking the whip, but as gentle and patient as a loving mother with an obstinate child. In other words, relaxation can never be acquired by force, constraint or violence.
In time, relaxation could become a habit, not a mechanical one, but an effortless conscious way of life. One can remain relaxed under the most exasperating conditions. Whatever they may be, one is relaxed, neither tense nor frowning with worry.
