It is also true that numerous meditation traditions that have come to the West have many people teaching in them without the foggiest idea that they are not at all qualified to do so. The canonical and commentarial texts state that we should have at least crossed the A&P Event to teach, though in the primary tradition I come from they consider second path as the standard minimum requirement for any sort of teaching. Basically, chancing into a path is impressive, but being able to tag another one demonstrates reproducible competence.
