To establish mindfulness and full awareness in daily life relies on a skilful filtering of the input of stuff coming at us from all directions, because the sheer deluge of contact can overwhelm them: what we give attention to receives our energy and enters our hearts, and there it stimulates action and reaction. Because we consequently build up bright or dark habits, we need to be responsible about what we give attention to. Part of cultivation is therefore about turning away from input and actions that just pull the mind out into craving or aversion or distraction. …Fathoming attention then is an action that causes us to pause, and takes us into our minds and hearts more deeply.
