It was his opinion that the touchstone of true devotion is the regulation of exercises of piety according to one's state of life. He often compared devotion to a liquid which takes the form of the vessel into which it is put. Here are his words to Philothea on the subject [1]: "Devotion," he says, "must be differently practised by a gentleman, by an artisan, by a servant, by a prince, by a widow, by a maiden, by a wife, and not only must the practice of devotion be different, but it must in measure and in degree be accommodated to the strength, occupations, and duties of each individual. I ask you, Philothea, would it be proper for a Bishop to wish to lead the solitary life of a Carthusian monk? If a father of a family were as heedless of heaping up riches as a Capuchin; if an artisan spent the whole day in church like a monk; if a monk, like a Bishop, were constantly in contact with the world in the service of his neighbour, would not the devotion of each of these be misplaced, ill-regulated, and laughable? Yet this mistake is very often made, and the world, which cannot or will not distinguish between devotion and indiscretion in those who think themselves devout, murmurs against and blames piety in general, though in reality piety has nothing to do with mistakes such as these." He goes on to say: "When creating them, God commanded the plants to bring forth their fruits, each according to its kind; so He commands christians, who are the living plants of His Church, to produce fruits of devotion, each according to his state of life and calling." At the close of the same chapter, our Blessed Father says: "Devotion or piety, when it is real, spoils nothing, but on the contrary perfects everything. Whenever it clashes with the legitimate calling of those who profess it, you may be quite certain that such devotion is spurious. 'The bee,' says Aristotle, 'draws her honey from a flower, without injuring that flower in the least, and leaves it fresh and intact as she found it.'" [Footnote 1: _The Devout Life_. Part i. c, 3.] WHAT IT MEANS TO BE A SERVANT OF GOD. Some think that they are not making any progress in the service of God unless they feel sensible devotion and interior joy continually, forgetting that the road to heaven is not carpeted with rose leaves but rather bristling with thorns. Does not the divine oracle tell us that through much tribulation we must enter the Kingdom of Heaven? And that it is only taken by those who do violence to themselves? Our Blessed Father writes thus to a soul that was making the above mistake:
