One is what might be called last-time meditation, in which you acknowledge that because you are mortal, there will be a last time for everything you do. There will be a last time you flip a light switch, a last time you eat dinner, and a last time you say goodbye to your parents, spouse, children, and friends. You have already done some things for the last time: there is a very good chance, for example, that you will never again dial a rotary telephone, type on a typewriter, or take a math exam. There will be a last time you lay your head on a pillow, as well as a last time you take a breath.
