AC 5962 - morning, midday, evening in the spiritual world; AC 5963 - tranquility of peace

AC 5962 [2,3]
In heaven . . . spirits and angels have
their morning, midday, and evening, also twilight,
and again morning, and so on.
It is their morning when the Lord is present
and blesses them with manifest happiness:
 they are then in the perception of good.
It is their midday when they are in the light of truths;
and it is their evening when they are removed therefrom,
and then it appears to them
that the Lord is more remote and is hidden from them.
All who are in heaven undergo
and pass through these alternations,
and cannot otherwise be continually perfected . . ..
It is worthy of admiration
that to eternity one state is never exactly like another,
and also that one spirit and angel does not pass through
the like changes of state as another,
for the reason that one is not exactly like another
in respect to good and truth;
just as neither is one man exactly like another in the face.
Nevertheless out of these varieties the Lord makes a one.

AC 5963
The varying states in the other life . . . 
are according to the perception of good and truth
with those who are there,
thus according to their perception
of the Lord's presence.
According to this perception
they have tranquility;
for they who are in the perception of the Lord's presence
are in the perception
that each and all things which befall them
tend to their good,
and that evils do not reach them;
consequently they are in tranquility.
Without such faith or confidence in the Lord
no one can possibly come to the tranquility of peace,
thus neither to the bliss in joy,
because this bliss dwells in the tranquility of peace.
