The prayers in this booklet were composed by St. John Eudes.They have been used by bishops, seminary professors, missionaries, and laity from all walks of life, to deepen their relationship with God. Within the book, you will find litanies, written to be prayed in two voices, alternating like a heartbeat. You will find passages from scripture, rearranged into poetry that can make your heart sing. The saint held a special devotion to the Sacred Heart and the Immaculate Heart, to the point where he considered them to act as a single Heart.
