179. There are levels of love and wisdom, consequent levels of warmth and light, and also levels of atmosphere. Without a knowledge that there are levels, what they are and what they are like, what is to follow will be incomprehensible, since there are levels in everything that has been created; therefore they exist in every form. Consequently, I need to discuss levels in this part of Angelic Wisdom.

We can tell clearly from the angels of the three heavens that there are levels of love and wisdom. Angels of the third heaven so surpass angels of the second heaven in love and wisdom, and these in turn so surpass angels of the farthest heaven, that they cannot live in the same place. Their levels of love and wisdom mark them off and separate them. This is why angels of the lower heavens cannot climb up to angels of the higher heavens, and why if they are allowed to climb up they do not see anyone or anything around them. The reason they do not see anyone is that the love and wisdom of the higher angels is on a higher level, a level beyond their perception. Every angel actually is her or his love and wisdom; and love together with wisdom is human in form because God, who is love itself and wisdom itself, is human.

Occasionally I have been allowed to see angels of the farthest heaven go up to angels of the third heaven. When they managed to get there, I heard them complain that they could not see anyone; and yet they were surrounded by angels. They were afterwards told that these angels had been invisible to them because they could not perceive their love and wisdom, and it is love and wisdom that give angels their human appearance.

23. There is one human God who is the source of everything. All the elements of human reason unite in, and in a sense center on, the fact that a single God is the Creator of the universe. As a result, rational people, on the basis of their shared understanding, neither do nor can think in any other way. Tell people of sound reason that there are two creators of the universe and you will feel within yourself how they recoil from this notion, perhaps simply from the tone of their voice in your ear. This enables us to see that all the elements of human reason unite and center on the oneness of God.

There are two reasons for this. The first is that in its own right, our very ability to think rationally is not our own property. It is a property of God within us. Human rationality in general depends on this fact, and this general property causes our reason more or less spontaneously to see the oneness of God. The second is that through our rational ability either we are in heaven's light or we draw from it some general quality of its thought, and the all-pervading element of heaven's light is that God is one.

This is not the case if we have used our rational ability to skew our lower understanding. In this case we still possess the ability, but by the distortion of our lower abilities we have steered it off course, and our rationality is not sound.
