In this physical world, we use them to form the concepts of our thinking and therefore the way we understand things. If we stay engaged with them and do not raise our minds above them, there is no way we can grasp anything spiritual and divine. We entangle such matters in concepts drawn from space and time, and to the extent that we do, the light of our discernment becomes merely earthly. When we use this light to think logically about spiritual and divine matters, it is like using the dark of night to figure out things that can be seen only in the light of day. Materialism comes from this kind of thinking.
However, when we know how to raise our minds above images of thought derived from space and time, we pass from darkness into light and taste things spiritual and divine. Eventually we see what is inherent in them and what they entail; and then we dispel the darkness of earthly lighting with that [new] light and dismiss its illusions from the center to the sides.
People who possess discernment can think on a higher level than these properties of nature—can think realistically, that is—and see with assurance that Divinity, being omnipresent, is not within space. They can also see with assurance the other things already mentioned. If they deny divine omnipresence, though, and attribute everything to nature, then they do not want to be lifted up even though they could be.
These two properties of nature—the space and time just mentioned—are left behind by everyone who dies and becomes an angel. At that time, people come into a spiritual light in which the objects of their thought are truths, and the objects of their vision—even though those objects look like things in this physical world—are actually responsive to their thoughts.
The objects of their thought, which as just noted are truths, are not at all dependent on space and time. While the objects of their sight do seem to be in space and in time, angels do not use them as the basis for their thinking. The reason is that in the spiritual world intervals of space and time are not fixed the way they are in our physical world, but are changeable in response to their states of life. This means that states of life take the place of space and time in the concepts of their thinking. Issues related to states of love are in place of spatial intervals and issues related to states of wisdom are in place of temporal intervals. This is why spiritual thought and the consequent spiritual speech are so different from earthly thought and its speech that they have nothing in common. They are alike only as to the deeper aspects of their subject matter, which are entirely spiritual. I need to say more about this difference later [Sections 163, 295, and 306].
Since angels’ thoughts do not depend at all on space and time, then, but on states of life, we can see that angels do not understand when someone says that Divinity fills space. They do not know what spatial intervals are. They understand perfectly, though, when someone says that Divinity fills everything, with no reference to any image of space.
