I love it, when I hear a phrase or definition that for a moment, changes everything. For instance this: "unmixed attention is prayer."
I think this works well with the Zen idea that everything we do; meditating, mowing the lawn, bouncing a ball, singing a song, writing a poem or play, painting a picture, running on the lakefront, taking the next sip of coffee - done with complete unmixed attention/awareness - can be transcendant.
It is up to us. What do we bring to what we do? If we open ourselves completely, focus on all that surrounds us, take it in without preconception, with total clarity, can we transform ourselves and the world that we live in?
