1029. Superficial calluses are brought on by the bodily memory, and the more tightly they hang on to that memory, the more solid and thick the calluses are. But the things which do not stick in that memory are wiped away. This is actually caused by the very inward elements acting on it, which reshape it in their own image.
1029. The external calluses are induced by means of the corporeal memory, and the more closely they are fixed in that memory, the more solid and dense they are. The things, however, which are not fixed in that memory are obliterated, and this by the more interior things which operate into them, and reduce them to their own form.
1029. Externi calli inducuntur per memoriam corpoream, quo enim arctius isti memoriae inhaerent, eo sunt solidiores et densiores, at quae in ista memoria non haerent, obliterantur, et quidem ab intimioribus, quae operantur in ea, et ad sui formam reducunt.
