In IE3 class we are supposed to read a paragraph about the meanings of the circle in world and comment it about Japan here. I couldn't find a good one but I'll put it on.
"Ensō is a Japanese word meaning "circle" and a concept strongly associated with Zen. Ensō is one of the most common subjects of Japanese calligraphy even though it is a symbol and not a character. It symbolizes absolute enlightenment, strength, elegance, the universe, and the void; it can also symbolize the Japanese aesthetic itself. As an "expression of the moment" it is often considered a form of minimalist expressionist art."
It was little of Buddhism but I don't believe in Buddhism so much.
