マニ車, or "mani wheel," is a traditional Buddhist prayer wheel used primarily in Tibetan Buddhism. It consists of a cylindrical drum that is mounted on a spindle, allowing it to be spun. Inside the wheel are scrolls containing mantras, which are sacred phrases or prayers. Spinning the wheel is believed to release the prayers into the universe, promoting spiritual benefits for the spinner. These wheels can vary in size, from small handheld versions to large structures found in monasteries. マニ車 are often adorned with intricate designs and symbols, reflecting the rich artistic traditions of Tibetan culture. They serve as a tool for meditation and a means to accumulate merit in Buddhist practice.
