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.

84. Because these two worlds are so distinct from each other, it is quite obvious that the spiritual world is under a different sun than is the physical world. There is just as much warmth and light in the spiritual world as there is in the physical world, but the warmth there is spiritual and so is the light. Spiritual warmth is the good that thoughtfulness does and spiritual light is the truth that faith perceives.

Now, since the only possible source of warmth and light is a sun, it stands to reason that there is a different sun in the spiritual world than there is in the physical world. It also stands to reason that because of the essential nature of the spiritual world's sun, spiritual warmth and light can come forth from it, while because of the essential nature of the physical world's sun, physical warmth [and light] can come forth from it. The only possible source of anything spiritual--that is, anything that has to do with what is good and true--is divine love and wisdom. Everything good is a result of love and everything true is a result of wisdom. Any wise individual can see that this is their only possible source.
