The Rosary is a form of prayer used in the Catholic Church that involves the repetition of prayers and meditation on specific events in the lives of Jesus Christ and the Virgin Mary. It consists of a string of beads, typically 59, which help the user keep track of the prayers. The main prayers include the Our Father, Hail Mary, and Glory Be. The Rosary is divided into five sets of ten beads, known as decades, each representing a particular mystery. These mysteries are categorized into the Joyful, Sorrowful, Glorious, and Luminous mysteries, guiding the faithful in their reflections during prayer.
