◎[Does Confrontation with the Devil Occur Immediately?] - 2
◎Confrontation with the Devil is in the Second Mansion
The Interior Castle is composed of seven mansions. Six of these mansions surround the seventh, where the Lord of Glory dwells, but the devil appears in the second mansion.
Regarding the point of whether confrontation with the devil occurs immediately and how to overcome it, the reason for it being the second mansion is subtle, but the basic understanding that it is overcome through intellect is comprehensible.
"But here, in this second mansion, the devils wage many kinds of subtle and terrible war upon the soul, and the soul suffers incomparably more than in the first. For in the first mansion the soul was very dull of hearing and understanding, like a person who is deaf and understands little; and the devil did not take so much trouble with it, because he thought it had no power to wound him and that his hopes of conquering it were small. But here, as the understanding becomes more lively, and the faculties begin to waken, the devils use such cunning that the soul must have great help from God if it is to escape them. For the enemy now attacks it openly and tries to inspire it with fear by representing the hardships and trials which those who serve God have to suffer, and by persuading it that they cannot persevere in them because of their weakness. He pictures to it the pleasures of the world and makes it think that these will last for ever; he recalls to its memory its relatives and friends and the good times which it used to enjoy; he represents to it how bad its health will be if it leads such a life of penance, and suggests other things of the same kind. For, as I have said, when souls begin to enter these mansions, they have always the greatest desire to make amends for their sins. The devil sets before them countless hindrances to this and with these the soul has to do battle in the second mansion.
O Jesus! What storms the devil rouses in this mansion, and what weariness and disquiet the poor soul suffers, not knowing whether to go forward or to return to the first! On the other hand, the reason shows it the deceitfulness of the devil and makes it reflect that all the things which he sets before it are nothing in comparison with what it is seeking. Faith tells it that its treasure is not where the devil would have it seek it. Memory pictures to it the death of those who have enjoyed the pleasures of the world and shows how quickly all earthly things come to an end and how suddenly some people die and how quickly they are forgotten. It reminds it, too, how many of those who lived in great prosperity are now in hell, and how the soul itself has already passed by their graves and seen the countless worms which are consuming their bodies. Memory recalls to it these and many other things.
(Omission)
The will is inclined to love Him Who has bestowed so many favours and shown it such great love; and it desires to repay Him in some way for this love. It is borne in upon the soul that this true Lover never leaves it but always goes by its side and gives it its being and its life. Finally the understanding teaches it that, however many years it may live, it will never find a better friend than He. It also makes it realize that all the things of this world are vanity and deceitfulness and that the pleasures which the devil sets before it are accompanied by many trials and afflictions and disquiet."
