The handheld prayer wheel ({{Transliteration|bo|mani lag 'khor}}) has a cylindrical, generally sheet-metal body (often beautifully embossed) mounted on a metal shaft or pin set into a wooden or metal handle that turns on a circular bearing commonly made of ''Turbinella'' (conch) shell. The cylinder itself is affixed with a cord or chain terminating in a small weight allowing it to be spun by a slight rotation of the wrist. The weighted chain, known as a “governor” in Western technology, stabilizes the wheel and keeps it spinning with less input from the practitioner than would otherwise be the case. When the prayer wheel is spun in prayer, the mantras inside become potent with the person's intent, allowing the practitioner to accumulate wisdom and merit.{{citation needed|date=November 2021}}

==== Large wheels ====

Prayer wheels larger than human size are to be seen in separate rooms in [[Tibetan Buddhism|Tibetan Buddhist]] temples and can be set in motion by pilgrims. With the help of a small bell the number of revolutions can be counted. The cylinders of fixed prayer wheels are often inscribed with the formula “[[Om mani padme hum]]” (meaning “jewel in the lotus”) in ornamental Lantsa ([[Ranjana script|Ranjana]]) letters.<ref>{{Citation |last1=Lama |first1=Dalai |title=FOREWORD |date=2014-11-05 |work=My Tibetan Childhood |pages=ix–x |url=https://doi.org/10.2307/j.ctv1220jm6.3 |access-date=2024-12-11 |publisher=Duke University Press |last2=Gyatso |first2=Tenzin|doi=10.2307/j.ctv1220jm6.3 }}</ref>

==== Row installations ====
Many monasteries around Tibet have large, fixed, metal wheels set side by side in a row. Passersby can turn the entire row of wheels simply by sliding their hands over each one. They are set in motion by pilgrims who [[Parikrama|circumambulate]] the building in a clockwise direction.{{Citation needed|date=February 2024}}
