120. Man knows nothing at all of the interior state of his mind or
internal man, yet infinite things are there, not one of which comes to
his knowledge. His internal of thought or internal man is his very
spirit, and in it are things as infinite and innumerable as there are in
his body, in fact, more numerous. For his spirit is man in its form, and
all things in it correspond to all things of his body. Now, just as man
knows nothing by any sensation about how his mind or soul operates on all
things of the body as a whole or severally, so he does not know, either,

spirit. The divine activity is unceasing; man has no part in it; still
the Lord cannot purify a man from any lust of evil in his spirit or
internal man as long as the man keeps the external closed. Man keeps his
external closed by evils, each of which seems to him to be a single
entity, although in each are infinite things. When a man removes what
seems a single thing, the Lord removes infinite things in it. So much is
implied in the Lord's purifying man from the lusts of evil in the
internal man and from the evils themselves in the external.

renouncing the world and devoting oneself to piety; others still by
confessing oneself guilty of all sins; and so on. And yet none of these
