The Course’s term (used only in M-2, M-3, and M-4) for a teacher-pupil relationship, which is a situation in which a teacher is teaching and a pupil is learning. This situation need not be formal—our most important teachers are often simply people we respect and whose example we follow. It need not be overtly spiritual—the Course mentions two students walking home together and becoming friends (M-3.2). And it need not be long-term—it can be a brief encounter on an elevator (M-3.2). But the ultimate goal of each teaching-learning situation is for it to become a holy relationship, in which teacher and pupil join in a single goal and gradually learn to overlook all the differences between them and see the face of Christ in each other. When this holy relationship is achieved, both are bumped ahead immeasurably on their journey. The pupil becomes a teacher of God and the teacher becomes an advanced teacher.
