St. Gertrude the Great (1256–1302), a German Benedictine nun, is celebrated as one of the Church’s most cherished mystics. From her earliest years, she dedicated herself to God, combining remarkable intellect with profound humility. As Abbess, she guided her sisters with wisdom and compassion, teaching them to find trust and rest in Christ’s presence. Her life was marked by continual visions, in which Our Lord revealed His Sacred Heart, spoke words of comfort, and bestowed heavenly favors.

This volume presents both her life and the extraordinary revelations that followed: encounters with Christ, the Virgin Mary, and the saints; teachings on prayer, the value of suffering, and the power of the sacraments—especially the Eucharist. Many of her visions are tied to the feasts and seasons of the Church, making her mystical experiences a guide for Christian life throughout the year. Together they reveal God’s infinite tenderness and mercy, offering inspiration, encouragement, and a deeper call to devotion for every reader.
