The practices of acceptance and non-attachment are critical to Zen and Buddhist practice, but they are easily misunderstood. It can sound like we're being asked not to care about things, or not to try to change things for the better. Fortunately, this is not what Zen means by acceptance or non-attachment, because 1) it's impossible (or psychologically and spiritually damaging) not to care, and 2) trying to change things for the better is the bodhisattva path itself!
