The "Heart of Mary" refers to the deep love and compassion that the Virgin Mary, the mother of Jesus Christ, is believed to embody. It symbolizes her maternal care, devotion, and the emotional suffering she experienced during her life, particularly during the crucifixion of her son. This devotion is often expressed in various forms of art, prayer, and religious practices within the Catholic Church. Devotion to the Heart of Mary is closely associated with the concept of the Immaculate Heart of Mary, which emphasizes her purity and role as a spiritual mother. Many believers seek her intercession, believing that her heart represents a model of love and fidelity to God. This devotion encourages followers to cultivate similar virtues in their own lives.
