Cover art for Eclipse lyrics by Kirlian Camera

I interpret this song as talking about the the transience of existence. Our existence/life is just a brief moment in time. Like an eclipse, it is wonderful and beautiful but only remains for a short moment. Then it is gone and in the past.

A take it this way: Out existence/life is basically meaningless, but we can still enjoy how wonderful it is as long as it lasts.
