Concentration is the practice of happiness. There is no happiness without concentration. When you eat an orange, try to practice concentration. Eat it in such a way that pleasure, joy and happiness are possible the whole time. You look at the orange, and breathe in such a way that it reveals itself as the miracle it is. An orange is nothing less than a miracle. It is just like you–you are also a miracle of life. you are a manifest miracle.
-Thich Nhat Nhanh
