AC 4110 - three kinds of spirits; AC 4111 - changes of state

AC 4110 [2]
There are good spirits,
there are spirits of a middle sort,
and there are evil spirits,
who are adjoined to a person during his regeneration,
to the end that by their means
he may be introduced into genuine goods and truths,
and this by the Lord by means of angels;
but they are such spirits or societies of spirits
as are not in agreement with the person to be regenerated,
except for a time;
and therefore, when they have performed their use,
they are separated.
Their separation is effected in various ways -
that of the good spirits in one way,
that of the spirits of a middle sort in another way,
and that of the evil spirits in still another way.
The separation of the good spirits
is effected without their being aware of it,
for they know that of the Lord's good pleasure
it is well with them wherever they may be,
or wherever they may be by Him transferred.
But the separation of the spirits of a middle sort
is effected by many means,
even until they withdraw in freedom.
. . . The evil spirits also are indeed removed in freedom,
but in a freedom which only appears to them as freedom.
They are adjoined for the purpose of introducing
opposing ideas and feelings which are to be rejected,
in order that the person may be
the better confirmed in truths and goods;
and when he begins to be confirmed in these,
they perceive a discomfort in remaining,
and a delight in separation,
and in this manner they are separated in a freedom
that comes of their delight.
Such is the case with the separation
of the spirits from a person when he is being regenerated,
and consequently with the changes of his state
as to good and truth.

AC 4111 [3]
For speaking generally,
the changes of state in the other life
are nothing else than
approaches to the Divine
and removals from the Divine.
