I found this great article on the use of the
Orthodox Prayer Rope also called Chotki or
Komboskini . I hope you enjoy it.
There are two ways we can pray using the prayer rope:
At any time of the day when we have free time, without being seen by anyone, secretly, we hold the prayer rope with our left or right hand and move from knot to knot with our thumb whispering simultaneously or meditating upon the prayer: "Lord Jesus Christ have mercy on me" or "Most Holy Theotokos save us".
At the time of our regular prayer, when we pray following the rule of prayer that our spiritual father has told us to follow, we hold the prayer rope with our left hand between the thumb and the index finger and move from knot to knot. At each knot we simultaneously do two things: i) with our right hand we make the sign of the cross over ourselves and ii) we say the prayer "Lord Jesus Christ have mercy on me". When we finish with all the knots of the prayer rope, we continue following the same procedure, for as many times as our spiritual father has told us to.
We hope that all our brothers and sisters in Christ will be helped by this little book, which is the result of the experience of an anonymous Monk of the Holy Mountain Athos. We also hope that everyone will use the prayer rope in the way our Holy Fathers have taught us, even if one lives in a society and not in a monastery.
