Calligraphy is Dō. More accurately it’s a Dō called Shodō. I think it’s interesting that calligraphy is Dō not only in Japan but in many places, From the Benedictine monks in the middle-ages, through the beautiful Arab calligraphy and to the ancient Jewish profession of hand writing the whole Bible – Sofer Stam. Maybe that is how Dō develops, out of the need to write down a grocery list, out of the duty to write in your tax form, out of the wish to preserve the scriptures.
