Flow is being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and you're using your skills to the utmost.

Art is an explosion, and the explosion itself is art. 艺术是一种爆炸，而爆炸本身就是艺术。

虚无是道的本体，因缘是道的作用。
