"Oh Raffaelina, what a consolation it is to know one is always in the care of a celestial spirit, who does not abandon us (how admirable) even when we disgust God! How sweet is this great truth for the believer! Who, then, does the devout soul fear who tries to love Jesus, having always close by such a great warrior? Oh, was he not one of the many who, together with the Angel Saint Michael, up there in the Empyrean, defended the honour of God against Satan and against all the other rebellious spirits, and finally reduced them to perdition and bound them in hell?
Well, know that he is still powerful against Satan and his satellites; his charity has not diminished, nor will he ever fail in defending us. Develop the beautiful habit of always thinking of him; that near us is a celestial spirit, who, from the cradle to the tomb, does not leave us for an instant, guides us, protects us as a friend, a brother; will always be a consolation to us especially in our saddest moments.
Know, oh Raffaelina, that this good Angel prays for you; offers to God all the good works you accomplish; your holy and pure desires. In the hours when you seem to be alone and abandoned, do not complain of not having a friendly soul to whom you can unburden yourself and in whom you can confide your sorrows. For pity's sake, do not forget this invisible companion, always present to listen to you; always ready to console you.
Oh delicious intimacy, oh blessed company! Oh if all men could understand this great gift that God, in His excess of love for man, assigned to us; this celestial spirit. Often remember his presence; you must fix on him the eyes of your soul; thank him; pray to him; he is so refined, so sensitive. Respect him; be in constant fear of offending the purity of his gaze.
Invoke often this Guardian Angel, this benevolent Angel and repeat the beautiful prayer: 'Oh Angel of God' (etc.) ... What will be, oh my dear Raffaelina, the consolation when, at the moment of death, your soul will see this Angel, so good, who accompanied you through life and was so liberal in maternal care. Oh may this sweet thought make you grow always more fond of the Cross of Jesus, this being also what your good Angel wants. May the desire to see this inseparable companion arouse in you that charity which incites you to leave this body quickly.
Oh what a holy and salutary thought it is to want to see this our good Angel. it is this thought which should make us want to leave this dark prison in which we are bound. Oh, Raffaelina, where do my thoughts fly to now...? Treat this dear little Angel, I do not say as a friend, but as one of the family. And, to tell you the truth, this little Angel does not seem to be the least little bit offended by my treatment of him. How dear and how good he is."
