AC 4041, 4048 - Heaven and the Brain

AC 4041

The heavenly form is amazing,
and quite surpasses all human intelligence;
for it is far above the ideas of the forms
that a person can possibly conceive of
from worldly things,
even with the aid of analysis.
All the heavenly societies are arranged in order
in accordance with this form,
and wonderful to say
there is a gyration according to these forms,
of which angels and spirits are not sensible.
This is like the daily movement
of the earth round its axis,
and its annual movement round the sun,
which its inhabitants do not perceive.
It has been shown me
of what is the nature of this heavenly form
in the lowest sphere;
it was like the form of the circumvolutions
seen in the human brains.
It was given me to perceptibly see this flow
(that is, these gyrations),
and this continuously for several days;
and in this way I was assured
that the brain is formed in accordance with
the form of the flow of heaven.
But the interior things therein,
which do not appear to the eye,
are in accordance with the interior forms of heaven,
which are quite incomprehensible;
and I was told by the angels
that from this it can be seen
that mankind has been created
according to the forms of the three heavens;
and that in this way
the image of heaven has been impressed upon him,
so that a person is a little heaven in the least form;
and that this is the source
of his correspondence with the heavens.

AC 4048

There was one who spoke to me close to my head,
and I perceived from the sound
that he was in a state of tranquillity
like that of a kind of peaceful sleep.
. . . those who were like him
relate to the longitudinal sinus,
which is between the two hemispheres of the brain,
and is there in a quiet state,
however much the brain may be in tumult
on both sides of it.
