Prayer wheels are a very common sign in places where Buddhism is present. They are usually aligned around Buddhist shrines and are set in motion by devotees. Each wheel is filled in with small pieces of paper, each inscribed with Om mani padme hum mantra. Buddhists believe that each revolution is as meritorious as reading the inscription aloud as many times as it is written on the pieces of paper inside the wheel.
