chotki
A chotki, also known as a prayer rope, is a string of beads used in Eastern Orthodox Christianity. It is an important spiritual tool for prayer and is typically made from wool or silk. The number of knots can vary, but commonly ranges from 33, 50, 100, or 300. Each knot is usually a small tassel or loop, and the beads themselves are often made of wood, seeds, or glass.
The chotki serves as a tactile aid for prayer, helping the user keep track of the number
The origin of the chotki is attributed to Saint Anthony of Egypt in the 4th century, though
