Nature triumphant
Eroding man's vanity
Inviting new life

(An English haiku has three lines with five, seven, and five syllables, respectively. There are shorter and longer versions, but this is the official definition, since that is the closest we have to Japanese on. This has no seasonal reference, although the subject is nature, which fits tradition. I do not know whether this truly embraces kiru, the cutting juxtaposition.)
