42. It is the same with love and wisdom, the only difference being that the substances and forms that are love and wisdom are not visible to our eyes as are the organs of our external senses. Still, no one can deny that those matters of love and wisdom that we call thoughts, perceptions, and feelings are substances and forms. They are not things that go floating out from nothing, remote from any functional and real substance and form that are their subjects. There are in fact countless substances and forms in the brain that serve as the homes of all the inner sensation that involves our discernment and volition.

What has just been said about our external senses points to the conclusion that all our feelings, perceptions, and thoughts in those substances and forms are not something they breathe out; they themselves are functional and substantial subjects. They do not emit anything, but simply undergo changes in response to the things that touch and affect them. There will be more later [210, 273] on these things that touch and affect them.

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.
