In the Orthodox traditions of Turkey, Greece, Romania, and Russia, using prayer beads of knotted ropes is a monastic devotion, often (but not always) reserved for men. Depending on the particular tradition, a prayer strand may have 100 or 103 beads. A Romanian Orthodox prayer rope made to be worn on the wrist has 33 knots. While most rosaries are strung in the traditional circular form, Russian Orthodox beads are strung in such a way as to resemble a ladder, a theme in keeping with the general Orthodox belief that prayer is the primary way for the soul to make its spiritual ascent to heaven. Central to Orthodoxy is a continual repetition of the Jesus Prayer: Lord, Jesus Christ, Son of God, have mercy on me as a sinner. The prayer is a means of achieving a spiritual union with God, and the rope is used to count the number of times the prayer is said.
