Happiness is a by-product, not an end in itself. It is like health – if you do the right things, if you eat the right food, a balanced diet and so on, you are healthy; but if you eat the wrong food and yet search for health, obviously it doesn’t exist. So happiness is something that cannot be sought after – it happens. When it happens, don’t cling to it. If you cling to it, it becomes a memory, and the moment it becomes a memory, it is a dead thing.
