Thank you for your response!
In his preface to the book, St. Francis called the person he addresses “Philothea” which he explained is “a name signifying one who loves God, or at least desires to do so.”
St. Francis de Sales encourages that the meditations in Introduction to the Devout Life be read and prayed “one after another, in the order in which they come, only taking one each day.” We encourage you to read the rest of the meditations in the book as part of your daily spiritual nourishment! Various editions are always in print, and certain ones are available online for free.
