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.”

56. One may believe that a doctrine of genuine truth can be acquired by means of the Word’s spiritual sense, which is obtained through a knowledge of correspondences. But doctrine is not acquired by means of that sense, but is only illustrated and corroborated by it. For as we said in no. 26 above, no one arrives at the spiritual sense through correspondences unless he first possesses genuine truths from doctrine. If he does not possess genuine truths first, a person may falsify the Word by applying some correspondences that he knows and connecting them and interpreting them to support something lodged in his mind from a preconceived premise.

In addition, the spiritual sense is granted to a person only by the Lord, and He protects it, as He protects heaven, inasmuch as heaven is present in it.

It is better, therefore, for a person to study the Word in its literal sense. That alone is the source of doctrine.
