Mani stones are stone plates, rocks and/or pebbles, inscribed with the six syllabled mantra of Avalokiteshvara / Chenrezig (Om mani peme hung), hence the name "Mani stone", as a form of prayer in Tibetan Buddhism. The term Mani stone may also be used in a loose sense to refer to stones on which any mantra or devotional designs are inscribed. Mani stones are intentionally placed along the roadsides and rivers. Creating and carving mani stones as devotional or intentional process art is a traditional sadhana of piety to yidam.
