The control of the breath: reading books cannot give anyone the control of the breath. For this, practice is needed. Reading the theory of music cannot make anyone a composer, a singer, a piano player. Ask the composers, the singers, the violinists how much they have to practice. The practice of the breath is very difficult and very arduous. We see the yogis sitting for hours in the same position, standing in the same position, practicing for hours in the night or before dawn. By the control of the breath all things are gained. If a man is a great writer, it is because his breath holds the thoughts that are in his mind. Sandow, by the control of breath, developed ideal muscles. Before the control of the breath is learnt, there is the control of the body. This is gained by the practice of postures and positions. If a small child is trained once in the day to sit still for five minutes or four minutes, not to run about, that gives control. If it is trained not to begin to eat at dinner until everybody eats, that gives control.
