An indirect metaphor for the fleeting nature of existence

"The end of the race is just a temporary marker without much significance. It's the same with our lives. Just because there's an end doesn't mean existence has meaning. An end point is simply set up as a temporary marker, or perhaps as an indirect metaphor for the fleeting nature of existence. It's very philosophical - not that at this point I'm thinking how philosophical it is. I just vaguely experience this idea, not with words, but as a physical sensation." (#23 p.115)
