joy is peace and peace is joy

Author Anne Lamott writes that her pastor Veronica says that "peace is joy at rest, and joy is peace on its feet." (Plan B, p. 7) I haven't heard peace and joy described this way before, but I get it. It is how I feel when I am throwing, glazing, or recycling clay.....I feel peace as the wheel spins in front of me, and I become one with the clay, as we shape together a bowl or plate, and joy is the activity bubbling around, the hum of the wheel and the radio blasting, my body working and aching and the voices of the studio busy in creation around me. It is active, and peaceful...a wonderful connected yin yang circle of fullness.
