Darkness so profound
When, at length, they have practiced themselves for some time in the journey of virtue, persevering in meditation and prayer, wherein, with the suavity and relish they have found, they have become detached from worldly things, and acquired some spiritual strength in God, so as to be able to curb the creature appetites and in some small degree suffer for God some slight load and dryness, without turning back at the crucial moment; when, to their thinking, they are proceeding in these spiritual exercises to their entire satisfaction and delight; and when the Sun of Divine favors seems to them to shine most radiantly upon them, God darkens all this light, and shuts the door and fountain of the sweet spiritual water, which they were wont to drink in God as often and as long as they chose … and thus, he leaves them in darkness so profound that they know not whither to direct the sense of the imagination and speculations of the mind.
