Joy is not happiness — it is the sudden sense that the world is, despite all evidence, fundamentally all right. Nasreddin found it in unexpected places: in the moment he realized he had lost something, in the laughter following a failed plan, in the donkey that was never where he left it. You cannot pursue joy directly; you can only create the conditions in which it occasionally appears, like a cat that comes to you the moment you stop calling.
Each step builds on the last.
