In short, there are faculties in man which, by the artificiality of his life, are closed, and man lives an incomplete life. To live a full life the wise in all religions have taken the breath in hand and awakened atoms and centers which are instruments for those faculties. As soon as breath touches those centers it makes them vibrate and then they do their work. Therefore breathing exercises given to a mureed are like the winding of a clock. Once in twenty-four hours the clock is wound and after that it goes on without effort.
