AC 4040, 4041, 4054 - the heavenly form, the brain, and ends and uses

AC 4040
When the brain is denuded of the skull
and the coverings that encompass it,
wonderful sinuously curving and
overlapping masses of tissue are visible,
in which there are deposited
what are called the cortical substances.
From these run out fibers
which constitute the medulla of the brain.
These fibers proceed from there
by way of nerves into the body
and perform functions there as the brain bids and chooses.
All of this is in perfect accord with the heavenly form,
for such a form is imprinted by the Lord on the heavens,
and from the heavens on the things within the human being,
in particular on his cerebrum and cerebellum.

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 (movement) 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.

AC 4044
Representations are nothing but images
of spiritual things in natural ones,
and when the former are rightly represented in the latter,
the two correspond.
. . . as there is nothing that can subsist from itself,
but only from some other,
and this again from some other,
and finally from the First,
and this by a nexus of correspondences,
they who enjoy some extension of judgment
 may draw the conclusion
that there is a correspondence between a person and heaven;
and further, between heaven and the Lord who is the First.

AC 4054
The brain, like heaven,
is in the sphere of ends which are uses;
for whatever flows in from the Lord
is an end looking to the salvation of the human race.
This end is that which reigns in heaven,
and thereby reigns likewise in the brain;
for the brain, which is where the mind is,
looks to ends in the body,
in order that the body may serve the soul,
so that the soul may be happy to eternity.
. . . For it is the end that makes the person,
and such as is the end,
such is the person;
consequently such is his human after death.
