Arcana Coelestia #658
658. Those three degrees which in general are called those of the human understanding - that is to say, intellect, reason, and knowledge - are also meant, as has been stated, by the windows for the three storeys of the Temple in Jerusalem, 1 Kings 6:4, 6, 8. They are also meant in what has appeared earlier by the rivers that went out of the garden of Eden from the east, where 'the east' means the Lord, 'Eden' love which belongs to the will, 'the garden' resulting intelligence, and 'the rivers' wisdom, reason, and knowledge. For these matters, see what has been stated at Genesis 2:10-14.
Genesis 2:10-14
10
A river went out of Eden to water the garden; and from there it was parted, and became four heads.
11
The name of the first is Pishon: this is the one which flows through the whole land of Havilah, where there is gold;
12
and the gold of that land is good. There is aromatic resin and the onyx stone.
13
The name of the second river is Gihon: the same river that flows through the whole land of Cush.
14
The name of the third river is Hiddekel: this is the one which flows in front of Assyria. The fourth river is the Euphrates.
