" An emotion is like a cloud passing through the sky. Sometimes it is fear or anger, sometimes it is happiness or love, sometimes it is compassion. But none of them ultimately constitute a self. They are just what they are, each manifesting its own quality. With this understanding, we can cultivate the emotions that seem helpful and simply let the others be, without aversion, without suppression, without identification. "
