Tibetan Buddhists believe that saying the mantra (prayer) Om Mani Padme Hum, 
invites the blessings of Chenrezig, the embodiment of compassion.



They also believe you can produce the same effect by spinning the written form of the mantra 
around in a prayer wheel (called "Mani wheels" by the Tibetans). The effect is said to be 
multiplied when more copies of the mantra are included, 
and spinning the Mani wheels faster increases the benefit as well. 

His Holiness, the Dalai Lama, has said that having the mantra on your computer 
works the same as a traditional Mani (prayer) wheel. 
As the digital image spins around on your hard drive, it sends 
the peaceful prayer of compassion to all directions 
and purifies the area.
