Mani Stone, called as Ya Ze in Tibetan area in Jiuzhaigou, is originated from the belief of the Bön religion that everything in the world has its own life. It is the representation of the piety to the Mountain deity in the original Bön. religion. Ya Ze are stones or various wooden weapons piled up at the appointed location at the top of sacred mountains or along the mountain pass. Sutra texts are inscribed on them and sutra streamers are set upon them too.

The location of Ya Ze is set by Tulku or eminent monks according to the location of sacred mountains and celestial bodies. Monks or masters are in charge of the establishment of Ya Ze. It is believed to have many benefits such as blessing for peace, stabilization of villages, abundance of treasure, thriving and good health of both human being and livestock and avoidance of tragedy. Some Ya Ze are used as the dividing signal of two areas.
