EVEN THOUGH EVERYTHING in heaven appears to be located in space just like things in our world, still angels have no notion or concept of location and space. Since this can only seem like a paradox, and since it is highly significant, I should like to shed some light on it.
All motion in the spiritual world is the effect of changes of inner states, to the point that motion is nothing but change of state. This is how I have been led by the Lord into the heavens and also to other planets in the universe. This happened to my spirit, while my body remained in the same place. This is how all angels move about, which means they do not have distances; and if they do not have distances, they do not have space. Instead they have states and their changes.
This being the nature of motion, we can see that drawing near is likeness of inner state and moving away is dissimilarity. This is why the people who are nearby are the ones in a similar state and the ones who are far away are in dissimilar states. It is why space in heaven is nothing but the outward states that correspond to the inner ones.
This is the only reason the heavens are differentiated from each other, as are the communities of each heaven and the individuals in each community. It is also why the hells are completely separate from the heavens: they are in an opposite state.
