An Emperor once commissioned a ring that would make him sad when he was happy and happy when he was sad. The sage engraved four words: “This too shall pass.” Years later, sitting in a damp dungeon after a coup, the Emperor looked at his ring and smiled. He knew the wheel hadn't stopped; it was simply halfway through its turn. By the time the guards came to execute him, he felt like a king again, and by the time his son took the throne, the boy was already a future prisoner.
