256. In its own right, the earthly level of the human mind is a continuum, but because of its responsiveness to the two higher levels, it seems to have distinct levels when it is raised up. Even though it is hard for people to understand this if they are not yet familiar with vertical levels, it still needs to be disclosed, since it is a matter of angelic wisdom. While earthly-minded people cannot think about this wisdom the way angels do, they can still grasp it mentally if their minds are raised into the level of light that angels enjoy. Our minds can actually be raised that far and enlightened accordingly. However, this enlightenment of our earthly minds does not happen by distinct levels. There is instead a gradual increase, and in keeping with that increase, our minds are enlightened from within, with the light of the two higher levels.

We can understand how this happens by perceiving that for vertical levels, one is above the other, with the earthly level, the terminal one, acting like an inclusive membrane for the two higher levels. As the earthly level is raised toward a higher level, then, the higher activates that outer earthly level from within and enlightens it. The enlightenment is actually happening because of the light of the higher levels from within, but it is received gradually by the earthly level that envelops and surrounds them, with greater clarity and purity as it ascends. That is, the earthly level is enlightened from within, from the light of the higher, distinct levels; but on the earthly level itself, it happens gradually.

We can see from this that as long as we are in this world and are therefore focused on the earthly level, we cannot be raised into wisdom itself, the way it is for angels. We can be raised only into a higher light at the boundary of angels and receive enlightenment from their light, which flows into us from within and illumines us.

I cannot describe this any more clearly. It is better understood through its effects; for if we have some prior knowledge about causes, their effects embody and present them in the light and thereby make them clear.

163. There would be no creation if it were not for this pair of suns, one living and one dead. Generally speaking, the universe is divided into two worlds, a spiritual one and a physical one. Angels and spirits are in the spiritual world, and we are in the physical world. These two worlds are exactly alike in outward appearance, so much alike that there is no way to tell them apart; but as to inner appearance, they are completely different. The very people who are in the spiritual world (who are called angels and spirits, as I have just said) are spiritual beings; and since they are spiritual beings, they think spiritually and talk spiritually. On the other hand, we who are in the physical world are physical, so we think physically and talk physically. Spiritual thought and speech and physical thought and speech have nothing in common. We can see from this that the two worlds, the spiritual one and the physical one, are completely distinct from each other, so much so that there is no way for them to be in the same place.
