I like the term Mono No Aware. It made me think about why the guy in the Rivers and Tides video was doing what he was doing. Maybe just to prove it could be done? That he could do it? I'm not sure. I assume he knew it wouldn't exist forever but he wanted to see it anyway. Part of creating something, to me, is getting that very initial "ah" moment or surprise. To see something you made exist into being. But I also feel that the longer something exists, like a piece of art , it almost immediately drops in the value of "ah-ness". Its permanent now. It's not going anywhere. So, it loses part of that elusiveness. When we make something we sometimes become anxious for its completion. I WANT to see this. Will I get this done? Will it ever be done? What if it falls apart? What if I don't like it in the end? For a moment, it becomes something so fragile, distant, and tender. But the second it is finished, that feeling leaves you. So to create something with the intent of it not being permanent...almost gives it an eternal elusiveness because it will only last for so long. So we try to treasure the moments it does exist. And by doing that, I feel he will always love the art he made and remember as a fond personal moment in time with that art.
