21. (8) Consequently the heavenly joys, which the angels have only from this source, are countless, and hardly one of that countless number is known in the world, because today adultery reigns there, even as a result of falsity of doctrine; but they were known in part to the most ancient men.

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.
