This is just a philosophical question, but wouldn't perfection be slightly on the boring side...just as if everyone was beautiful, what would be the point? Japanese artists add an imperfection purposefully. I think it is the rough edges we have, the little lapses, the tiny errors, the wrinkles, the creases, the signs that we have lived that make us interesting. Why would we want perfection when there is such a fascinating mystery and wonderful bewilderment to the imperfect? Just wondering. Has nothing to do with the poem which seems to speak of a very fragile soul indeed.
