May God be pleased to give me His light, that I may speak profitably of this; for I have great need of it while treating of a night so dark and speak… - John of the Cross

The soul is purified also in this aridity of the desires from the imperfections of the other three capital sins of which I have spoken,7 envy, anger, and sloth, and acquires the opposite virtues. Softened and humbled by these aridities, by the hardships, temptations, and afflictions which in this night try it, it becomes gentle with God, with itself, and with its neighbor. It is no longer impatiently angry with itself because of its own faults, nor with its neighbor because of his; neither is it discontented or given to unseemly complaints against God because He does not sanctify it at once. As to envy, the soul is in charity with every one, and if any envy remain, it is no longer vicious as before, when the soul was afflicted when it saw others preferred to it, and raised higher; for now it yields to every one considering its own misery, and the envy it feels, if it feels any, is a virtuous envy, a desire to emulate them, which is great virtue.

In this night the soul obtains these four benefits here mentioned, namely, delight of peace, constant remembrance of God, purity and cleanness of soul, the practice of all the virtues of which I have just spoken. So David speaks from his own experience when he was in this night. “My soul,” he says, “refuses to be comforted; I was mindful of God and was delighted, and was exercised, and my spirit fainted.” He adds forthwith: “I meditated in the night with my own heart, and I was exercised, and I swept my spirit”6 clean of all affections.
