"Breathing is one of the simplest things in the world. We breathe in, we breathe out. When we breathe with real freedom, we neither grasp for nor hold onto the breath. No effort is required to pull the breath in or to push the breath out. Given the simplicity of breathing one would think it was the easiest thing to do in the world. However, if it were truly so easy there would be few unhappy or unhealthy people in the world. To become a welcome vessel for the breath is to live life without trying to control, grasp, or push away. And how easy is this? The process of breathing is the most accurate metaphor we have for the way that we personally approach life, how we live our lives, and how we react to the inevitable changes that life brings us.
