What it is
Written around 1712 as a personal spiritual letter to a devout religious sister in Nantes, this short treatise presents the same doctrine of total consecration to Jesus through Mary as the longer Traité, but in condensed form accessible as a single sitting's reading; it also contains the distinctive section 'The Tree of Life,' a meditation on the soul's spiritual growth through Mary. It survived only in two handwritten copies held by Montfort's religious congregations and was not published until 1868; since then it has appeared in over 400 editions and 40 languages. Together with the Traité it forms the doctrinal core of Montfortian Marian spirituality.
Why it still matters
Because it distils the full consecration doctrine into a brief, accessible text, The Secret of Mary is an ideal introductory guide for Christians new to Marian consecration, or as a compact daily review during the 33-day preparation period before making the total consecration.

Abandonment to Divine Providence
L'Abandon à la Providence divine
A spiritual treatise assembled from letters and conference notes that Jean-Pierre de Caussade, SJ wrote to the Nuns of the Visitation at Nancy between 1733 and 1740, where he served as spiritual director. Mother Sophie de Rottembourg grouped passages from his correspondence into eleven thematic chapters; this manuscript circulated in Visitandine houses before Henri Ramière published a reworked version in 1861 under the title L'Abandon à la Providence divine. The text's governing idea is total surrender to what Caussade calls 'the sacrament of the present moment' — the conviction that God's will is encountered fully in each immediate circumstance. Though addressed to enclosed religious women, the letters were recognized from the outset as broadly applicable to devout laypeople navigating the anxieties of life, and they circulated among spiritually serious court and convent circles in France during the mid-Bourbon era.
The Adventures of Telemachus
Les Aventures de Télémaque, fils d'Ulysse
Written by Fénelon in the early 1690s as private instructional reading for his charge Louis, Duke of Burgundy—grandson of Louis XIV and presumed heir to the French throne—this didactic prose epic follows Telemachus and his mentor Mentor through allegorical encounters with kingdoms of virtue and vice. Fénelon was formally appointed tutor to the Duke in 1689. The work was never intended for publication; the first Paris edition appeared in 1699 from the widow of Claude Barbin with a royal printing privilege, and a pirated Hague edition also circulated that year. Louis XIV recognised the implied critique of his absolutism and wars and suppressed the book, but it was already unstoppable: it became the most widely reprinted work of French prose fiction in the eighteenth century, with over 300 editions between 1701 and 1801, and was described by contemporaries as the most-read book in France after the Bible.
Règlement pour les enfants
Règlement pour les enfants de Port-Royal
Jacqueline Pascal — younger sister of Blaise, nun at Port-Royal des Champs — composed this Rule for Children in 1657 when she held charge of the convent school, the same year she was named sub-prioress and mistress of novices. The text is a detailed formation manual for the Jansenist petites écoles, describing how the teaching nun functions as spiritual director for her pupils, leading them in communal prayer, scriptural commentary, the chapter of faults, and personal interviews. The school educated daughters of the devout Jansenist nobility and bourgeoisie, and the Règlement is the most direct document of how Port-Royal transmitted its spirituality to the next generation through structured formation.
