In the short term, the Mindfulness of Breathing practice helps us to become more calm and (rather paradoxically) to become more energized and refreshed.
In the long term, it helps us to develop more awareness so that we have more freedom to choose what our responses are going to be in any given situation. This means, for example, that we can find ourselves in a situation that would normally make us anxious, but we can choose instead to cultivate patience and calmness.
Practicing mindfulness is enormously enriching. Instead of being half-aware of what we’re doing, we can fully and richly experience every moment of our lives. The mindfulness that we develop in this practice will help us to enjoy our food more, will help us to concentrate better at work, and will help us to be more present when we’re talking to our friends. And many people who do this practice last thing at night say that it helps them to sleep and that their dreams are richer.
Mindfulness helps us develop the ability to pay sustained attention, and this is valuable in many ways. Ultimately it’s because we’re able to pay sustained attention to our experience that we’re able to gain spiritual insight. Without this ability we simply skim over the surface of our experience without really learning anything. With it we learn more and more about how to become happier and more fulfilled.
