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.

242. Spiritual light flows in within us through three levels, but not spiritual warmth except to the extent that we abstain from evils as sins and turn to the Lord. What I have presented thus far indicates that light and warmth emanate from the sun of heaven, that sun, described in part 2, that is the first emanation of divine love and wisdom. The light emanates from his wisdom and the warmth from his love. Further, the light is the vessel of wisdom and the warmth is the vessel of love; and the more we are engaged in wisdom, the more we come into that divine light, and the more we are engaged in love, the more we come into that divine warmth.

We can also tell from what has been presented that there are three levels of light and three levels of warmth, or three levels of wisdom and three levels of love, and that these levels are formed within us in such a way that we are open to divine love and wisdom and therefore to the Lord.

The present task, then, is to show that while spiritual light flows in through these three levels in us, spiritual warmth does not--except to the extent that we abstain from evils as sins and turn to the Lord; or what amounts to the same thing, to show that we can accept wisdom all the way to the third level, but not love--unless we abstain from evils as sins and turn to the Lord; or (what again amounts to the same thing) to show that our discernment can be raised up into wisdom, but our volition cannot be raised up [into love]--except to the extent that we abstain from evils as sins.
