Nepalese Prayer Wheel

The prayer wheel (Tibetan: mani chos 'khor; Nepali: mani chakra) is a cylindrical device filled with tightly rolled paper or metal sheets inscribed with mantras — most commonly Om Mani Padme Hum, the mantra of Avalokiteshvara, the Bodhisattva of compassion. Each rotation of the wheel is considered equivalent to verbally reciting all the prayers contained within it once. A single prayer wheel may contain millions of mantra repetitions printed in tiny script, meaning a single spin generates the merit of millions of prayers — making the device an extraordinary efficiency mechanism for the accumulation of spiritual merit.

The theological basis for the prayer wheel's efficacy in Tibetan Buddhism lies in the understanding that the power of a mantra is not dependent on the speaker's conscious awareness of its meaning — the sound vibration itself creates the spiritual effect. Just as wind blowing through prayer flags inscribed with mantras is considered to spread the mantras' blessings across the landscape, a prayer wheel turning in a person's hand continuously radiates the blessings of its contained mantras in all directions. This understanding makes the prayer wheel one of the most practical and compassionate inventions in world religion: even while walking, working, or resting, the practitioner generates merit for all beings.

Prayer wheels come in sizes ranging from small hand-held versions to enormous fixed wheels at monastery entrances that take two hands and a full body rotation to spin, to water-powered prayer wheels at river banks that spin continuously day and night without human intervention. In Nepal and Tibet, passing a row of prayer wheels and spinning each one with the right hand as you walk by is one of the most common acts of daily devotional practice — a mobile prayer that takes no time away from other activities.
