Which treats of interior locutions that may come to the spirit supernaturally. Says of what kinds they are.

THE discreet reader has ever need to bear in mind the intent and end which I have in this book, which is the direction of the soul, through all its apprehensions, natural and supernatural, without deception or hindrance, in purity of faith, to Divine union with God. If he does this, he will understand that, although with respect to apprehensions of the soul and the doctrine that I am expounding I give not such copious instruction neither do I particularize so much or make so many divisions as the understanding perchance requires, I am not being over-brief in this matter. For with respect to all this I believe that sufficient cautions, explanations and instructions are given for the soul to be enabled to behave prudently in every contingency, outward or inward, so as to make progress. And this is the reason why I have so briefly dismissed the subject of prophetic apprehensions and the other subjects allied to it; for there is so much more to be said of each of them, according to the differences and the ways and manners that are wont to be observed in each, that I believe one could never know it all perfectly. I am content that, as I believe, the substance and the doctrine thereof have been given, and the soul has been warned of the caution which it behoves it to exercise in this respect, and also concerning all other things of the same kind that may come to pass within it.

2. I will now follow the same course with regard to the third kind of apprehension, which, we said, was that of supernatural locutions, which are apt to come to the spirits of spiritual persons without the intervention of any bodily sense. These, although they are of many kinds, may, I believe, all be reduced to three, namely: successive, formal and substantial. I describe as successive certain words and arguments which the spirit is wont to form and fashion when it is inwardly recollected. Formal words are certain clear and distinct words[456] which the spirit receives, not from itself, but from a third person, sometimes when it is recollected and sometimes when it is not. Substantial words are others which also come to the spirit formally, sometimes when it is recollected and sometimes when it is not; these cause in the substance of the soul that substance and virtue which they signify. All these we shall here proceed to treat in their order.
