The effectual offset to this painful condition is repose.
The art of inducing a condition of repose can be readily acquired by any one who will carefully and faithfully do as follows: Place yourself in an easy lying or lounging position in a quiet place, with fresh air.

Physical repose prepares for and invites mental repose.

Now allow the mind to work care free at its own sweet will without any attempt to control it.

Close the eyes and _breathe slowly, gently, and deeply, with steady rhythm_.

In two or three minutes a sensation of quiet restful repose will be experienced, which may be continued for several minutes or may even lead to a natural sound sleep.
This result may not be attained at the first or the second trial, but a few repetitions of the exercise will insure success in almost every case.
