"Souls will be unable to reach perfection who do not strive to be content with having nothing, in such fashion that their natural and spiritual desire is satisfied with emptiness; for this is necessary in order to reach the highest tranquility and peace of spirit. Hence the love of God in the pure and simple soul is almost continually in act."

“Live as though only God and yourself were in this world, so that your heart may not be detained by anything human.”

“Deny your desires and you will find what your heart longs for. For how do you know if any desire of yours is according to God?”

“Love consists not in feeling great things but in having great detachment and in suffering for the Beloved.”

“Worldly people are in the habit of censuring those who give themselves up in earnest to God, regarding them as extravagant, in their withdrawal from the world, and in their manner of life. They say also of them that they are useless for all matters of importance, and lost to everything the world prizes and respects! This reproach the soul meets in the best way; boldly and courageously despising it with everything else that the world can lay to its charge. Having attained to a living love of God, it makes little account of all this; and that is not all: it confesses it itself in this stanza, and boasts that it has committed that folly, and that it is lost to the world and to itself for the Beloved.”

“When the soul, then, in any degree possesses the spirit of solitary love, we must not interfere with it. We should inflict a grievous wrong upon it, and upon the Church also, if we were to occupy it, were it only for a moment, in exterior or active duties, however important they might be. When God Himself adjures all not to waken it from its love, who shall venture to do so, and be blameless? In a word, it is for this love that we are all created. Let those men of zeal, who think by their preaching and exterior works to convert the world, consider that they would be much more edifying to the Church, and more pleasing unto God — setting aside the good example they would give if they would spend at least one half their time in prayer, even though they may have not attained to the state of unitive love.”
