The way I understand it, when Paul says not to label what you feel, he's saying not to judge it or attempt to classify it, especially not in terms of "good" and "bad" feelings. Simply notice the feeling as a feeling and fully experience it in all its texture in the present. In this way, we learn to accept whatever we feel for what it is, without any judgment or "labels," and that is the first step to living in the now, the goal of the living with full awareness.
