The title track of Van Morrison’s 1990 album Enlightenment opens with the lyrics “chop that wood, carry water,” a reference to the popular Zen Buddhist dictum that before enlightenment, one must chop wood and carry water, and that after enlightenment, one must chop wood and carry water. The origin is a verse by the late eighth-century Chinese poet ­Layman Pang, who declared that his “supernatural power and marvelous activity” was “drawing water and carrying firewood.”
