THE RETAINED BREATH.
(1) Stand erect. (2) Inhale a complete breath. (3) Retain the breath as long as you can comfortably. (4) Exhale vigorously through the open mouth. (5) Practise the cleansing breath. At first you will be able to retain the breath only a short time, but a little practise will also show a great improvement. Time yourself with a watch, if you wish to note your progress.
