Mindfulness is meditation in action and involves a "be here now" approach that allows life to unfold without the limitation of prejudgment. 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.
~ from MINDING THE BODY, MENDING THE MIND by Joan Borysenko
The song of a river ordinarily means the tune that waters play on rock, root, and rapid....This song of the waters is audible to every ear, but there is other music in these hills, by no means audible to all. To hear even a few notes of it you must first live here for a long time, and you must know the speech of hills and rivers. Then on a still night, when the campfire is low and the Pleiades have climbed over the rimrocks, sit quietly and listen for a wolf to howl, and think of everything you have seen and tried to understand. Then you may hear it--a vast pulsing harmony--its score inscribed on a thousand hills, its notes the lives and deaths of plants and animals, its rhythms spanning the seconds and the centuries.
~ Aldo Leopold, "Song of the Gavilan" in A SAND COUNTY ALMANAC
