AC 2183 - the angels rule the rational and the evil spirits rule the natural

AC 2183 [2,3,4]
. . . to most people it is unknown
that every person has an internal, a rational, and a natural,
and that these are most distinct from each other,
so distinct, that one of them may be distinct from another;
that is, that the rational, which is called the rational person,
may be distinct from the natural, which is the natural person;
even that the rational person can even see and perceive the evil
which is in the natural person
and, if it is a genuine rational, may chastise it.
Before these two have been conjoined together,
a person cannot be an entire (or perfect) person,
nor can he be in the tranquility of peace,
for the one fights with the other.
For the angels who are with the person rule his rational,
but the evil spirits who are with him, his natural,
and so there comes combat.

If the rational then conquers,
the natural is subjugated,
and the person is thus gifted with conscience;
but if the natural conquers,
he can then receive nothing of conscience.
If the rational conquers,
his natural then becomes as if it also was rational;
but if the natural conquers,
the rational becomes as if it also was natural.
And further, if the rational conquers,
the angels then draw nearer into the person,
and insinuate to him charity
(which is the celestial that comes from the Lord through the angels),
and the evil spirits remove themselves to a distance;
but if the natural conquers,
the angels then remove themselves further away
(that is, more toward the person's interiors),
while the evil spirits draw nearer toward the rational,
and continually attack it,
and fill the lower parts of his mind
with hatreds, revenges, deceits, and the like.
If the rational conquers,
the person then comes into the tranquility of peace,
and in the other life into the peace of heaven;
but if the natural conquers,
then while the person lives
he appears as if he were in tranquility,
but in the other life he comes into the unrest and torment of hell.

In this way may be known what is the quality of a person's state
as to his rational, and as to his natural;
so that there is nothing else that can make a person blessed and happy
but that his natural be conformed to his rational,
and both be conjoined together.
This is effected solely by means of charity,
and charity is solely from the Lord.
