Love is frequently equated with good feelings toward others, with benevolence or nonviolence or service. But these things in themselves are not love. Love springs from awareness. It is only inasmuch as you see someone as he or she really is here and now and not as they are in your memory or your desire or in your imagination or projection that you can truly love them.
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.
