Any activity can be done with mindfulness. Talking on the telephone, cleaning your home, driving, working, and exercising can all be incorporated into a mindfulness practice.
Throughout the day, inwardly pause and become very aware of where you are, what you are doing, and how you are feeling. Try to do this in a way that doesn’t cast value judgments on your experience. For example, if you notice that you are nervous, don’t think “Oh, I’m nervous, that’s so stupid of me…” Simply note, “I am feeling nervous,” without evaluating whether it is good or bad. Just notice that the nervousness is present.
When mindfulness is the primary tool of meditation, the awareness that we apply to our breath (or to whatever our object–or focus–of meditation is, such as a word, image, sound, or physical sensation to which we return our attention after becoming distracted) can be expanded to include all physical and mental processes so that we may become more mindful of our thoughts and actions.
It is commonly thought that meditators hope to stop all thoughts and rest their minds in thoughtless peace. A common complaint of beginning meditators is that they cannot meditate well, because they cannot stop thoughts from arising in their minds. Actually, having thoughts is perfectly normal, and not a problem at all. In fact, it’s what’s supposed to happen! Dealing with thoughts is how mindfulness meditation works. When you notice that you are distracted by thoughts, gently bring your attention back to the object of your meditation. This is how you become able to relate differently to distractions and increase your ability to focus and concentrate.
