We say that the hand is in control when it can grasp something and hold the thing in its grasp. The fingers, we say, are in control when they move up and down the piano, when they strike B when B is wanted, they do not strike E. Control is in repose and activity both. Sometimes we find that we have become angry, we have become impatient, we have lost control of our mind. Before control of the mind is lost, the control of the breath is lost. More than a thousand times since I have been in the West people have said to me, "We cannot control our mind. We cannot keep our mind fixed on one point." The first step is to lessen the activity of the mind. When the thoughts come more slowly, this is the first step. And the first thing is to control the breath, to make it slow and regular. By this the health of the body is improved, and the health of the mind. In the Qur'an it is said, "Surely, we revealed it on the night of Power" (Sura 97, 1:5).
