862. CONCERNING THE CALLUS OR THE CORPOREAL AND WORLDLY THINGS WHICH FORM IT It is surprising that a mass which is composed of corporeal and worldly things should be represented as a hard callus, or as an external crust - a callus which in some cases appears quite gross and hard, while in others it is not visible, though it is nevertheless present. This callus is a mass of the fallacies of the senses, consequently of falsities, stuck together by the loves of self and of the world. It must indeed be softened, but not broken, for it has its roots from things interior, and this latter callosity from things still more interior. When this callus is represented as being taken away, as it appears to be in the sphere of spirits by a spiritual representation, there is a medullary body beneath which is then seen, almost as in man in whom the callus is represented by the bony skull, and the interiors by the medullary brain.
