"One of the benefits of the prayer wheel is that it embodies all the actions of the Buddhas and Bodhisattvas of the 10 directions. To benefit sentient beings, the Buddhas and Bodhisattvas manifest in the prayer wheel to purify all our negative karmas and obscurations, and to cause us to actualize the realizations of the path to enlightenment."
