Travelers to Tibet may find mani stones and mani stone mounds almost everywhere, in monasteries, beside villages, along paths and on mountains. Sometimes they are decorated with sheep and yak horns. Usually the universal mantra, Om Mani Padme Hum, is inscribed on these smooth stone plates, pebbles and rocks. Images of deities and great adepts and sutra texts are also common themes. Tibetan people build these unique works of art to show their piety to their deities and the Buddha's teachings. Upon encountering a mani stone mound, Tibetan people circumambulate it clockwise as a prayer offering for health, peace, and protection.
