These prayer ropes are used by Orthodox Christians as an aid to prayer, especially for the Jesus Prayer: "Lord Jesus Christ, Son of God, have mercy on me, a sinner." There is a profound Hesychast tradition of silence and contemplative life associated with this prayer and its practice. May the Lord enlighten our minds with its understanding! Most of these Prayer Ropes are made of black wool, in the more customary simple pattern. (Shown: large 100-knot size).
