Tibetan Prayer Wheel/ Khorlo
A prayer wheel is a cylindrical wheel (Tibetan: འཁོར་ལོ།, Wylie: khor lo) on a spindle made from metal, wood, stone, leather or coarse cotton. ... At the core of the cylinder is a "life tree" often made of wood or metal with certain mantras written on or wrapped around it.
The prayer wheel should be turned clockwise with a single-pointed concentration of body, speech, and mind. It is easy and fast to turn the prayer wheel and it does not require great physical strength or many repetitions. The activity is easy to do, the meaning and or purpose is great, and the benefit is great.
