Breathing is the connection between the mind and the body. When the mind concentrates on the breath, it focuses attention on the present moment. Breathing is the first step on the path to discover your spiritual nature. As you get the body to breathe correctly, the mind settles down, and that creates fertile ground to develop whatever spiritual nature exists within you.
A day filled with noise and voices can be a day of silence, if the noises become for us the echo of the presence of God, if the voices are, for us, messages and solicitations of God.
