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.”

57. 3. Genuine truth, of which doctrine ought to consist, is apparent in the Word’s literal sense only to people who are enlightened by the Lord. Enlightenment comes from the Lord alone, and it is found in people who love truths because they are true and apply them to useful life endeavors. Enlightenment in the Word is not found in others.

Enlightenment comes from the Lord alone because the Lord is present everywhere in the Word. The reason enlightenment is found in people who love truths because they are true and apply them to useful life endeavors is that they are in the Lord and have the Lord in them. For the Lord embodies His Divine truth. When this truth is loved because it is Divine truth — and it is loved when it is applied to useful endeavor — then the Lord is present in the person in that truth.

This, too, the Lord teaches in John:

In that day you will know that...you (are) in Me, and I in you. He who has My commandments and keeps them, is he who loves Me.... ...and I will love him and manifest Myself to him...and (I) will come to him and make (My) home with him. (John 14:20-21, 23)

And in Matthew:

Blessed are the pure in heart, for they shall see God. (Matthew 5:8)

These are the people who are enlightened when they read the Word, and with whom the Word shines and is translucent.
