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.

1974. As for the meaning of "evening and morning," in all phases of regeneration, both general and particular, the progression starts from evening, and tends toward morning. In general, the evening of those who are being regenerated is misery, temptations, despair, but they arrive at the morning. So also in detail, in all phases of regeneration one begins from evils, which are turned into good. And it is worth remembering that evil spirits begin, out of their own fantasies and passions, to arouse the person, but that these evils are turned into good in various ways. This has been revealed to me by experience lasting 3 years. So that is "evening and morning," and it applies to every least phase. Therefore it is the process not only of regeneration, but also of the perception of goodness. 1748, 16 May.
