Breath breaks the congestion which in the head produces confusion and in the heart depression, which covers the thoughts of others from one's perception, even from one's own intuition. A thought is better conveyed to another through breath than by speech, for a feeling put into words becomes half-dead. Feeling, in its own sphere, is fully living, and when conveyed from there through the breath, it reaches the mind to which it is sent. When a person has not developed his mind by concentration and tries to send his thought by breath he is not always successful. He is like a person trying to hit the target without ever having practiced in his life. It is practice which makes man perfect.
