"It is a beauty of things imperfect, impermanent, and incomplete," writes Leonard Koren, in Wabi-Sabi For Artists, Designers, Poets & Philosophers. "It is a beauty of things modest and humble." His near-namesake, Leonard Cohen, gets closer to the heart of things: "Forget your perfect offering/There's a crack in everything/That's how the light gets in." This isn't merely "accepting" imperfection, as countless lifestyle gurus would have us do. The imperfection is the point.
