2299. CONCERNING THOSE WHO WISH TO ENTER INTO DIVINE MYSTERIES BY NATURAL PHILOSOPHY, OR THE THINGS OF PHYSICS. When the discourse was concerning spirituals, that which was perceived by me with a spiritual idea was perceived by a certain one materially; as it were, small white lines, which was a sign that spirituals are conceived of materially, which yet are not material things, because they are the powers of substances. When, therefore, they [who depend] on physics or philosophy desire hence to enter into those things that are spiritual and belong to faith, then their material ideas remain which are thus represented in the other life. Such persons are very greatly afflicted in the other life when they hear the truths of faith, yea, even to [that pitch] of anxiety, that they suppose they can scarcely be cured. This was given me to know today by experience, from a certain spirit who was so long afflicted that they despaired of his [cerum for ejus, I think] being cured. But no disease or irremediable evil is given, because the power of the Lord is infinite.
