For example, every time you walk up and down the stairs in your house or place of work, pay close attention to every step, every movement, even your breathing. Be totally present. Or when you wash your hands, pay attention to all the sense perceptions associated with the activity: the sound and feel of the water, the movement of your hands, the scent of the soap, and so on. Or when you get into your car, after you close the door, pause for a few seconds and observe the flow of your breath. Become aware of a silent but powerful sense of presence. There is one certain criterion by which you can measure your success in this practice: the degree of peace that you feel within.
