Om Mani Padme Hum Tibetan Buddhists believe that saying the mantra (prayer), Om Mani Padme Hum, out loud or silently to oneself, invokes the powerful benevolent attention and blessings of Chenrezig, the embodiment of compassion. Spinning the written form of the mantra around in a Mani wheel (or prayer wheel) is also believed to give the same benefit as saying the mantra, and Mani wheels, small hand wheels and large wheels with millions of copies of the mantra inside, are found everywhere in the lands influenced by Tibetan Buddhism.
