I was shown what the form of heaven is like in its lowest
realm; it resembled the pattern of folds seen in human
brains. A perceptible view of its flow or circular motion
was granted to me, the demonstration lasting several
days.
From this experience I could tell that the form of the
brain matches the pattern of movement in heaven. The
deeper parts of the brain, invisible to the eye, match the
deeper structures of heaven, which are totally incomprehensible. The angels said this shows that we were created
to reflect the structure of the three heavens. So the image
of heaven is imprinted on us in such a perfect way that
we are a miniature heaven at its smallest scale, which is
why we have a correspondence with the heavens.
