The function of rosary beads is to count prayers. While most people associate rosary beads with Catholicism, Hindus, Muslims, Buddhists and Taoists also use rosary beads in their worship.
In the Catholic religion, rosary beads often consist of several decades, or sets of prayers. Each decade consists of one "Our Father" prayer, 10 "Hail Mary" prayers and one "Glory Be" prayer. Other prayers said while using a rosary include the "Fatima Prayer" and the "Apostle's Creed." To prevent the rosary prayers from becoming monotonous and mindless, many Catholic worshipers meditate on four different "mysteries," the Luminous, Joyful, Glorious and Sorrowful Mysteries. Each mystery consists of five events taken from the lives of Jesus and Mary.
