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.

157. The physical world's sun is nothing but fire and is therefore dead; and since nature has its origin in that sun, nature is dead. In no respect whatever can creation itself be attributed to the physical world's sun: it is due entirely to the spiritual world's sun. This is because the physical world's sun is totally lifeless, while the spiritual world's sun is alive, being the first emanation of divine love and wisdom. Anything that is lifeless does not effect anything on its own, but is activated; so to attribute any aspect of creation to a lifeless sun would be to attribute the work of an artisan to the tool in the artisan's hand.

The physical world's sun is nothing but fire, with all its life removed. The spiritual world's sun is a fire that has divine life within it.

The angelic concept of the fire of the physical world's sun and the fire of the spiritual world's sun is like this: divine life is internal to the fire of the spiritual world's sun and external to the fire of the physical world's sun. We can see from this that the activity of our physical sun is not autonomous but stems from a living force that emanates from the spiritual world's sun. Consequently, if the living force of that sun were withdrawn or removed, our sun would fail. This is why the worship of the sun is the lowest of all forms of worship of God. It is just as dead as the sun itself; so in the Word it is called an abomination.
