I was told by the person who commanded me to write that, as the nuns of these convents of Our Lady of Carmel need someone to solve their difficulties concerning prayer, and as (or so it seemed to him) women best understand each other's language, and also in view of their love for me, anything I might say would be particularly useful to them. For this reason he thought that it would be rather important if I could explain things clearly to them and for this reason it is they whom I shall be addressing in what I write -- and also because it seems ridiculous to think that I can be of any use to anyone else. Our Lord will be granting me a great favour if a single one of these nuns should find that my words help her to praise Him ever so little better. His Majesty well knows that I have no hope of doing more, and, if I am successful in anything that I may say, they will of course understand that it does not come from me. Their only excuse for crediting me with it could be their having as little understanding as I have ability in these matters if the Lord of His mercy does not grant it me.
