Dō (literally: “the Way”) is a path which leads to enlightenment.
Dō is the Japanese pronunciation of the Tao that Lao-tzu spoke of the in the Tao Te Ching, which typically manifests itself as an art which is practiced as a way of life. Dō is difficult concept to explain, since the Western tradition does not use arts, crafts, or sports as a means for teaching spiritual or ethical truths. The closest equivalent in Western philosophy would be to achieve araté through phronesis.
Dō and jutsu are linked, like the two sides of a coin -- however they are complements, not opposites. Dō is not opposed to jutsu; a serious commitment to jutsu will gradually reveal dō through a series of epiphanies.
