For the next seven days, find a quiet place and time and try the following:
Take a few moments each day (2-5 minutes) to focus on your breathing. With each breath you take, think the following "As I breathe in, I notice I am breathing in. As I breathe out, I notice I am breathing out."
Just notice your breath. Do you inhale/exhale through your nose or mouth?
Notice the air expanding your lungs as you inhale. Notice your lungs contracting as you push the air out with each exhale.
Is there a pause between the inhale and the exhale?
Is the inhale the same length as the exhale? Or is the exhale slightly longer?
Are your breaths smooth, choppy, or a little of both?
What else do you notice about your breath?
When your mind starts to wander, just notice it and bring your awareness back to your breath. (Notice that I said when your mind wanders, not if.)
Just practice noticing without judgment, without definition.
