By contemplating the impermanence of everything in the world, we are forced to recognize that every time we do something could be the last time we do it, and this recognition can invest the things we do with a significance and intensity that would otherwise be absent. We will no longer sleepwalk through our life. Some people, I realize, will find it depressing or even morbid to contemplate impermanence. I am nevertheless convinced that the only way we can be truly alive is if we make it our business periodically to entertain such thoughts.
