It is hard for a foreigner entering a strange country for the first time to get true and correct impressions of it. They will necessarily be surface ones and may therefore be misleading ones. In the same way, without this previous instruction and training, it is hard for a mystic to get true and correct reception of the revelatory experience. This is because his mind will unconsciously reflect its personal limitations into the reception, so that what he gets is not the experience itself, but the experience in conjunction with those limitations, and therefore under them. He does not get direct reception at all.
