I have always been jealous of artists. The smell of the studio, the names of the various tools, the look of a half-finished canvas all shout of creation. What do writers have in comparison? Only the flat paper, the clacketing of the typewriter or the scrape of a pen across a yellow page. And then, when the finished piece is presented, there is a small wonder on one hand, a manuscript smudged with erasures or crossed out lines on the other. The impact of the painting is immediate, the manuscript must unfold slowly through time.
Real haiku is the soul of poetry. Anything that is not actually present in one's heart is not haiku. The moon glows, flowers bloom, insects cry, water flows. There is no place we cannot find flowers or think of the moon. This is the essence of haiku. Go beyond the restrictions of your era, forget about purpose or meaning, separate yourself from historical limitations there you will find the essence of true art, religion, and science.
