Not forgetting

Removing old impurities does not mean forgetting things, forgetting the body, extinguishing the mind, (or) stopping thoughts; it is necessary to remove impurities in the midst of action in order to accomplish the task. This is because the Tao is alive, in movement; it is neither material not void. We use worldy realities to practice the reality of the Tao, and use human realities to cultivate celestial virtues; both striving and nonstriving, comprehending essence and comprehending life, the endless work must all be done in the midst of activity.
