Orthodox prayer ropes are usually soft and made of wool. The purpose is to help us concentrate, not necessarily to count. In the famous book, The Way of the Pilgrim, the pilgrim said the prayer 2,000, then 6,000, then 12,000 times. Is 12,000 Jesus Prayers better than 2,000? Absolutely not. Quantity has nothing to do with love, and a living relationship with Jesus. The pilgrim did 12,000, no more and no less, as an act of obedience to his spiritual father, not because he was "making progress." He also prayed much because that was his "heart's desire." Every prayer is an act of love, made to the Author of Love, Who is waiting expectantly for our desire, and our acceptance of His Love.
