The Fourth Noble Truth identifies "The (Middle) Way," for ending suffering. This is the Noble Eight Fold Path. And, it is the walking/living our life step by step that shifts us from willing to doing. Zen is about action, one might say we are "Zenning." Here is an example...pause and then read this sentence again. If you did indeed pause and read the above sentence again you not only were reading but following a direction. So we may know the terms but it is in day to day interpretation and action that we unfold the meaning. So we in Zen are not so much people of the Sutras as we are people of the "Doing," what we sometimes call living zen. We become "The Way" in doing the day.
