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.

363, 1. Love and wisdom, and the volition and discernment that come from them, constitute our very life. Hardly anyone knows what life is. When people think about it, it seems like something ethereal, something with no specific image. It seems like this because people do not know that only God is life and that his life is divine love and wisdom. We can see from this that the life in us is nothing else and that there is life in us to the extent that we accept it.

We know that warmth and light radiate from the sun and that everything in the universe is a recipient, growing warm and bright in proportion to its receptivity. The same holds true as well for the sun where the Lord is, whose radiating warmth is love and whose radiating light is wisdom, as explained in part 2. It is from these two emanations from the Lord as the sun, then, that life comes.

We can tell that life is love and wisdom from the Lord from the fact that we grow sluggish as love ebbs away from us and dull as wisdom ebbs away; and if they leave us completely, we are snuffed out.

There are many forms of love that have been given their own names because they are derivatives, such as desires, cravings, appetites, and their gratifications and delights. There are many forms of wisdom, too, like perception, reflection, memory, thought, and focus on a subject. Further, there are many forms that come from both love and wisdom, such as agreement, decision, and resolve to act, among others. All of these belong to both [love and wisdom], but they are assigned their names on the basis of what is dominant and nearer to hand.

Finally, our senses are derived from these two, our sight, hearing, smell, taste, and touch, with their own pleasures and satisfactions. The appearance is that our eye is seeing, but our discernment is seeing through our eye, which is why we ascribe sight to our discernment. The appearance is that our ear is hearing, but our discernment is hearing through our ear. This is why we speak of the attentiveness and listening that are actually functions of discernment as "hearing." The appearance is that our nostrils smell and that our tongue tastes, but discernment is smelling with its perceptiveness and is tasting as well; so we refer to perceptiveness as smelling and tasting, and so on. The wellsprings of all these functions are love and wisdom; we can therefore tell that these two constitute our life.
