From the Book "Spiritual Combat ((Scupoli)
Chapter 25: THAT, IN ORDER TO FIGHT SUCCESSFULLY AGAINST HIS ENEMIES, THE SOLDIER OF CHRIST MUST AVOID AS MUCH AS POSSIBLE ALL PERTERBATION AND DISQUIET OF MIND
"As to other sad and trying events, such as sickness, wounds, or loss of dearest friends, pestilence, fire, war, or such-like evils, though these, being painful to nature, are for the most part shunned by the men of the world, yet may we, by divine grace, not only desire, but even love them, as just chistisements upon the wicked and occasions of virtue to the just.
For therefore does Our Lord take pleasure in sending them; and thus, borne forward by His will, we shall pass with a calm and quiet spirit through all the bitterness and contradictions of this life. And be assured, that all disquiet on our part is displeasing in His sight: for, of whatever kind it be, it is never free from imperfection and always springs from some evil root of self love"
