They are noted for their wonderful voices, which are strong, smooth and clear, and have a wonderful trumpet-like carrying power.

They have practiced this particular form of breathing exercise which has resulted in rendering their voices soft, beautiful and flexible, imparting to it that indescribable, peculiar floating quality, combined with great power.

The exercise given below will in time impart the above-mentioned qualities, or the Yogi Voice, to the student who practices it faithfully.

It is to be understood, of course, that this form of breath is to be used only as an occasional exercise, and not as a regular form of breathing.
(1) Inhale a Complete Breath very slowly, but steadily, through the nostrils, taking as much time as possible in the inhalation.

(4) Rest the lungs by the Cleansing Breath.
