13. But because I have much to say hereafter of this sweetness, which our Lord gives to those who persevere in prayer, [5] I do not speak of it here; only this will I say: prayer is the door to those great graces which our Lord bestowed upon me. If this door be shut, I do not see how He can bestow them; for even if He entered into a soul to take His delight therein, and to make that soul also delight in Him, there is no way by which He can do so; for His will is, that such a soul should be lonely and pure, with a great desire to receive His graces. If we put many hindrances in the way, and take no pains whatever to remove them, how can He come to us, and how can we have any desire that He should show us His great mercies? 14. I will speak now--for it is very important to understand it--of the assaults which Satan directs against a soul for the purpose of taking it, and of the contrivances and compassion wherewith our Lord labours to convert it to Himself, in order that men may behold His mercy, and the great good it was for me that I did not give up prayer and spiritual reading, and that they may be on their guard against the dangers against which I was not on my guard myself. And, above all, I implore them for the love of our Lord, and for the great love with which He goeth about seeking our conversion to Himself, to beware of the occasions of sin; for once placed therein, we have no ground to rest on--so many enemies then assail us, and our own weakness is such, that we cannot defend ourselves. 15. Oh, that I knew how to describe the captivity of my soul in those days! I understood perfectly that I was in captivity, but I could not understand the nature of it; neither could I entirely believe that those things which my confessors did not make so much of were so wrong as I in my soul felt them to be. One of them--I had gone to him with a scruple--told me that, even if I were raised to high contemplation, those occasions and conversations were not unfitting for me. This was towards the end, when, by the grace of God, I was withdrawing more and more from those great dangers, but not wholly from the occasions of them. 16. When they saw my good desires, and how I occupied myself in prayer, I seemed to them to have done much; but my soul knew that this was not doing what I was bound to do for Him to Whom I owed so much. I am sorry for my poor soul even now, because of its great sufferings, and the little help it had from any one except God, and for the wide door that man opened for it, that it might go forth to its pastimes and pleasures, when they said that these things were lawful.
