In Swedenborg's works, “enlightenment” means an ordering and linking of truths in our minds by the Lord, so that we understand them more clearly and deeply than before. Perhaps because of his intense awareness of spiritual world influences on us, Swedenborg does not advocate us seeking our own enlightenment on what is true, but instead to acquire it through hearing and obeying what the Lord reveals to us through the Word.

When people read the Word as a holy book in order to know what’s true, and think about what they are reading, they are inviting the Lord to flow into their minds, and carry out this ordering and linking process.

When someone then tries to put those truths into the acts of his or her life, the order and enlightenment are much increased. Note that the Lord doesn’t reveal new truths this way, but simply casts new light on the truths that the person has freely acquired.

Such enlightenment can go on through this life on earth and on to eternity in heaven. Some translators of Swedenborg's Latin have used the word “illustration” instead of “enlightenment.”

59. The first step for these people is to acquire for themselves doctrine from the Word’s literal sense. This lights a lamp for them for their further progress. Then after they have acquired some doctrine and have a lamp thus lit, they see the Word in its light.

People who do not acquire doctrine for themselves, however, first inquire whether the doctrine delivered by others and accepted by the general body accords with the Word. And to whatever accords they assent, and from whatever does not accord they dissent. In this way the doctrine becomes their own, and through doctrine their faith.

But this is the case only with people who are not distracted by worldly affairs and have the sight to see. If these people love truths because they are true and apply them to useful life endeavors, they are enlightened by the Lord. All others who live in some measure in accordance with truths can learn from them.
