TCR 154 - Angels; TCR 155 - Enlightenment; TCR 156 - A Person's Spirit

TCR 154

All the angels in heaven are filled with the Lord,
for they are in the Lord and the Lord in them;
but nevertheless each speaks and acts
according to the state of his own mind,
some simply, some wisely, thus with infinite variety,
and yet every one speaks (and acts)
of himself from the Lord.

TCR 155

. . . enlightenment, which comes from the Lord,
is changed into varied forms of light and heat 
in every individual,
according to the state of his mind.

TCR 156

By a person's spirit, in the strict sense of the term,
is meant simply his mind,
for it is this which lives after death,
and is then called a spirit;
if good, an angelic spirit, and afterwards an angel;
but if evil, a satanic spirit, and afterwards a satan.
The mind of every person is the internal,
or real person, and is within the external person,
which constitutes its body;
therefore, when the body is laid aside at death,
the internal person is in a complete human form.
So they are mistaken who suppose
that a person's mind is only in his head.
