The first thing to do when you sit down is to pay attention to your in-breath and out-breath. Focus your attention entirely on your breathing. If you truly practice, your breath will become peaceful. This peaceful breathing will soothe both mind and body. This is the first priority of sitting meditation, to help us calm down. Once we are calm, we can see more clearly. And when our vision is no longer clouded, we see with more understanding, and we naturally begin to feel compassion for ourselves and for others. That is when true happiness becomes possible.
