The number "four" in the Bible represents things being linked together or joined. This is partly because four is two times two, and two represents the ultimate linking between our desire to be good and our understanding of truth. We can also see this in the fact that most buildings are rectangular, with the four sides linking together to make a whole. We also divide directions into four -- north, east, south and west -- and talk about the "four corners" of something meaning all of it. So our special thinking naturally looks at four sides as linking together into a whole.

6608. The light of understanding has been given to me, taken away, lessened, and moderated when I have been thinking, speaking, and writing. This has happened frequently, and I have been allowed to perceive the variations and differences. The actual light I perceived as illumination that shone on the substances of my inward sight just as the sun gives light to the physical organs of sight. This general illumination made matters of thought visible just as earthly objects become visible when the eye is supplied with light. I was told that those variations in the light of understanding arose from different kinds of contact with heavenly communities.
