AE 739 - protection of the spiritual; the difference in the sensual and the celestial

AE 739 [3,10]

For the spiritual man is in heaven
and the natural in the world,
and so far as heaven, that is, the Lord through heaven,
can flow in through the spiritual man into the natural,
so far evils and the falsities from the evils,
which, as was said, have their seat in the natural man,
are removed;
for the Lord removes them,
as He removes hell from heaven.
The interior degree with man can be opened in no other way,
because the evils and falsities that are in the natural man
keep it closed up;
for the spiritual degree, that is, the spiritual mind,
contracts itself
against evil and the falsity of evil of every kind
as a fibril of the body does at the touch of a sharp point;
for like as the fibers of the body contract themselves
at every harsh touch,
so does man's interior mind,
which is called the spiritual mind,
at the touch or breath of evil or the falsity from the evil.
But on the other hand, when things homogeneous,
which are Divine truths from the Word
that derive their essence from good,
approach that mind,
it opens itself;
yet the opening is effected not otherwise
than by the reception of the good of love
flowing in through heaven from the Lord,
and by its conjunction with the truths
that man has stored up in his memory,
and this conjunction is only effected
by a life according to Divine truths in the Word,
for when these truths come to be of the life
they are called goods.

. . . the sensual man believes that he knows all things,
and that nothing is concealed from him;
but not so the celestial man,
who knows that he knows nothing from himself
but only from the Lord,
and that what he does know is so little
as to be scarcely anything
as compared with what he does not know.
