The term BEADS USED IN PRAYER can be summarized as ROSARY, which is a set of beads used in prayer by Catholics. The ROSARY consists of a string of beads divided into five decades, each decade containing ten beads. During the recitation of the ROSARY, prayers are said on each bead, with the Hail Mary being the most common. The ROSARY is often used as a form of meditation and contemplation, and is believed to bring peace and spiritual growth.
