Happiness is the cessation of suffering. It is well-being. For instance, when I practice this exercise of breathing in, I’m aware of my eyes; breathing out, I smile to my eyes and realize that they are still in good condition. There is a paradise of form and colors in the world. And because you have eyes still in good condition, you can get in touch with the paradise. So when I become aware of my eyes, I touch one of the conditions of happiness. And when I touch it, happiness comes.
Thich Nhat Hahn
