Mani Stones - Tibet
Mani stones are prayer stones that are intentionally placed along roads or rivers. They are an offering of prayer to the protective spirits of the area. The creation and carving of these stones is a devotional art practice, and is similar in sentiment to Prayer Flags. In sparsely populated Tibet, Mani Stone mounds can take the place of prayer halls and shrines for some locals, who live in remote areas. Mani stones are also used in nearby Nepal.
