" Nothing is perfect, final, or fixed in this material world. As soon as we are tempted to believe it is, we’ve probably set ourselves up for disappointment. What we’re truly striving for is the permanence that we can count on, amid all the change and flux. And the most permanent, secure, and stable thing we can possess is a foolproof way to deal with impermanence, insecurity, and surprise. A real connection with some greater awareness of the wellspring of our being and our universe will always provide the ultimate relief and resolution. But, as an Arab proverb so appropriately counsels: Trust in Allah, and tie your camel. "
