Quoting TedG (from FilmsFolded.com)

"Some time ago, I had the opportunity to attend an Ichibana lecture and demonstration. It was given by those close to emperor and was tailored for westerners. That meant that there were plenty slides that contrasted western flower arranging with this highest Japanese art. The western values all had to do with perfect symmetry, balance, coherent, simple shapes. Each element should be beautiful by itself. Harmonies were all within this lovely melody of perfect pace. Bach.

Contrasted with this was the Ichibana we saw constructed before us. Dissymmetries, tension, motion and peace. Some elements were dead, even damaged. The base or container was as likely to be misshapen, even ugly. Where the western arrangements were music, this was life. It had soul, katachi. The whole thing was quite an experience for me and was my most visceral introduction to a corner of Japan that I have since enfolded into my own life and eye. At the root of this is dissymmetry (which is different from asymmetry), the presence of items that have sibling states which are not expressed. It gives a tension that springs, the pumps blood and makes real beauty because it provides space for the definition of beauty."
