"According to an ancient Sufi story, there lived a king... who was continuously torn between happiness and despondency. The slightest thing would cause him great upset or provoke an intense reaction, and his happiness would quickly turn into disappointment and despair. A time came when the king finally got tired of himself and of life, and he began to seek a way out. He sent for a wise man... reputed to be enlightened. When the wise man came, the king said to him, “I want to be like you. Can you give me something that will bring balance, serenity, and wisdom into my life?... He handed the king an ornate box carved in jade. The king opened the box and found a simple gold ring inside. Some letters were inscribed on the ring. The inscription read: This, too, will pass. “What is the meaning of this?” asked the king. The wise man said, “Wear this ring always. Whatever happens, before you call it good or bad, touch this ring and read the inscription. that way, you will always be at peace.” This, too, will pass."
