The Buddhist magazine Lion’s Roar has republished (from 2010) an article by Thich Nhat Hahn on mindfulness. Some quotes:
“Our true home is not in the past. Our true home is not in the future. Our true home is in the here and the now. Life is available only in the here and the now, and it is our true home.”
“There are those of us who are alive but don’t know it. But when you breathe in, and you are aware of your in-breath, you touch the miracle of being alive. That is why mindfulness is a source of happiness and joy.”
“Mindfulness practice should be enjoyable, not work or effort. Do you have to make an effort to breathe in? You don’t need to make an effort. To breathe in, you just breathe in. Suppose you are with a group of people contemplating a beautiful sunset. Do you have to make an effort to enjoy the beautiful sunset? No, you don’t have to make any effort. You just enjoy it.”
