In Genesis 1:16, this signifies goods and truths, or, in the opposite sense, evils and falsities. (Arcana Coelestia 1808)

In Matthew 24:29, this signifies knowledge of faith which falls from heaven. (Arcana Coelestia 32, 1984[3])

'Stars' signify the knowledge of truth and good. 'Stars' are frequently mentioned in the Word, and always signify goods and truths, but in an opposite sense, evils and falsities. In the same way, they signify angels, or societies of angels, in the opposite sense, evil spirits and their bands. When they signify angels, or societies of angels, then they are fixed stars, but when they signify evil spirits and their fellowships, then they are wandering stars. 'The seven stars' in Revelation 1, denote the knowledge of everything pertaining to good and truth, and so every variety of good and truth.

(References: Apocalypse Revealed 51)

There are two aspects to the life of each person. We might call them "heart" and "mind," a part of us that wants and feels and a part of us that thinks and knows. The Writings usually refer to these as the "will" and the "understanding." They are reflections, and receptacles, of the Lord's infinite love and infinite wisdom. Of the two, the heart or will is ultimately the most important. Who we actually are is determined by what we love, and the things in our heart ultimately determine our place in heaven (or hell). But the will is beyond our control; we can't force ourselves to want something good or to not want something bad; we can control our actions, but not our feelings. Because of this power, the Lord works subtly and carefully in our hearts, in ways we can't sense. Most of the work and interaction goes on in our minds through the working of what the Writings call "Divine Truth," which is essentially the Lord's entire essence expressed in a form that is compatible with our minds. When the Bible talks about the Lord's "spirit," it represents this operation of Divine Truth in our minds, the way he reaches out and embraces us, and invites us to embrace him back. And when the Bible talks about people having "spirit," it is talking about our minds when we embrace Divine Truth.
