192. This is not the place to reproduce the list of Marian exercises approved by the Magisterium. Some, however, should be mentioned, especially the more important ones, so as to make a few suggestions about their practise and emendation.
First of these exercises: reading the Bible.
193. The Council’s call for the “sacred celebration of the word of God” at significant moments throughout the Liturgical Year (Cf. SC 35, 4), can easily find useful application in devotional exercises made in honor of the Mother of the Word Incarnate. This corresponds perfectly with the orientation of Christian piety (Cf. Paul VI, Apostolic Exhortation Marialis Cultus, 30) and reflects the conviction that it is already a worthy way to honor the Blessed Virgin Mary, since it involves acting as she did in relation to the Word of God. She lovingly accepted the Word and treasured it in her heart, meditated on it in her mind and spread it with her lips. She faithfully put it into practice and modelled her life on it (Cf. Paul VI, Apostolic Exhortation Marialis Cultus 17; Collectio missarum de beata Virginis Mariae, Praenotanda ad lectionarium, 10).
Logical. But in my experience, most Marian devotion does not involve the Scriptures. The Directory on Popular Piety and the Liturgy is online at the Vatican site.
