I wasn't sure how to answer this at first.
Then I realised the context of the creation, books, movies, paintings, statues, poems...need not matter. Probably a cop out answer to some. But to me it's those...little beauties that are aflame for just one moment, one single moment of sincerity and then it blows out like a candle to the wind.
This has more to do with an individual's reaction to such stimulus than the stimulus itself usually. You can try to hold onto that brilliant moment of course, but in truth it can never really be held again, it's there and gone, even though the original object that excited such a reaction is viewed over and over again.
Because it was never the object to begin with it, it was the person's imagination, the singular most perfect gift any creature of nature could receive.
