I have one longing only: to grasp what is hidden behind appearances... What is my work? ... to let the mind fall silent that I may hear the Invisible calling.
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.
