"Whenever a wholesome thought arises, acknowledge it: "A wholesome thought has just arisen." If an unwholesome thought arises, acknowledge it as well: "An unwholesome thought has just arisen." Don't dwell on it or try to get rid of it. To acknowledge it is enough. If they are still there, acknowledge they are still there. If they have gone, acknowledge they have gone." - The miracle of Mindfulness by Thich Nhat Hanh.
"You don't drop-kick a puppy into the neighbor's yard every time it piddles on the floor. You just keep bringing it back to the newspaper. So I keep trying gently to bring my mind back to what is really there to be seen, maybe to be seen and noted with a kind of reverence." - Bird by Bird by Anne Lamott
"The art of living in this 'predicament' is neither careless drifting on the one hand nor fearful clinging to the past and the known on the other . It consists in being completely sensitive to each moment, in regarding it as utterly new and unique, in having the mind open and wholly receptive." - The Wisdom of Insecurity by Alan Watts
