Mindfulness is meditation in action and involves a "be here now" approach that allows life to unfold without the limitation of pre-judgment. It means being open to an awareness of the moment as it is and to what the moment could hold. It is a relaxed state of attentiveness to both the inner world of thoughts and feelings and the outer world of actions and perceptions.
For those of us with a hunger to know the truth, painful emotions are like flags going up to say, "You're stuck!"... such uncomfortable feelings are messages that tell us to perk up and lean into a situation when we'd rather cave in and back away. When the flag goes up, we have an opportunity: we can stay with our painful emotion instead of spinning out. Staying is how we get the hang of gently catching ourselves when we're about to let resentment harden into blame, righteousness, or alienation. It's also how we keep from smoothing things over by talking ourselves into a sense of relief or inspiration...With practice, however, we learn to stay with a broken heart, with a nameless fear, with the desire for revenge. Sticking with uncertainty is how we learn to relax in the midst of chaos, how we learn to be cool when the ground beneath us suddenly disappears. We can bring ourselves back to the spiritual path countless times every day simply by exercising our willingness to rest in the uncertainty of the present moment — over and over again.
