(Here is where the lady lived, for whom St. Francis de Sales wrote his classic spiritual work)

"...the Holy Spirit by the mouths of all the saints, and our Savior by His own, assure us that a devout life is a life above all others the most sweet, happy, and amiable. The world sees devout people fast, pray, suffer injuries, serve the sick, give alms to the poor, watch over themselves, restrain their anger, stifle their passions, deprive themselves of sensual pleasures, and perform other actions in themselves and by their own nature and character painful and rigorous. But the world does not discern the interior and heartfelt devotion that renders all these actions agreeable, sweet, and easy....

"Believe me, devotion is the delight of delights and the queen of virtues, for it is the perfection of charity."

~ St. Francis de Sales, Philothea: or, The Introduction to the Devout Life.
