Mindfulness means paying attention, on purpose, to whatever is going on in the present moment without passing judgment on it. This practice involves noticing something and holding it in your attention lightly, with gentle acceptance, like a butterfly resting on your hand, until it moves away on its own. In mindfulness, you attend to a feeling, thought, or sensation without clinging to it, resisting it, or trying to change it.
