“Preach my Psalter… if you want to reach hardened souls and win them over to God.”
This is part of a traditional account of the Blessed Virgin Mary appearing to St. Dominic and instructing him to use “her Psalter”—a reference to the 150 Hail Marys of the Rosary (mirroring the 150 Psalms). This message was central to his preaching mission.
