That is the wonderful thing about the breathing, and the reason it is such a helpful object of attention. It is both perfectly ordinary (we are all doing it, all the time) and extremely special (if we weren’t doing it, we’d be dead)… Everybody breathes. It is also extremely portable. We take it everywhere we go. So if you choose to practice with the breathing, it has the advantage of always being there. No matter how many times you forget it throughout the day, you can always take it up again. There’s another in-breath. There’s an out-breath.
