It's seldom that you know that you're having an experience for the last time. I'm aware that all of life consists of firsts since no two experiences are exactly the same and every experience is the last time, so it is valuable to live many experiences as though you were doing them for the last time. That's similar to live each day as if it were your last. If a person dies young or old, he can live with conscious completion. Getting old plays a big part in my being increasingly aware that any activity I do I may be doing for the last time,and that helps me to sometimes savor the moment with conscious completion and be aware of the giant miracle we live in. Small death is constantly happening, and we would do well to enjoy greater conscious completion ongoingly. Conscious completion doesn't make anything sacred; it is because everything is sacred that it makes sense to live with conscious completion.
