A prayer wheel is a cylindrical "wheel" (Tibetan: འཁོར་, Wylie: 'khor) on a spindle made from metal, wood, stone, leather or coarse cotton. Traditionally, the mantra Om Mani Padme Hum is written in Sanskrit on the outside of the wheel. Also sometimes depicted are Dakinis, Protectors and very often the 8 auspicious symbols Ashtamangala. According to the Tibetan Buddhist tradition based on the lineage texts regarding prayer wheels, spinning such a wheel will have much the same meritorious effect as orally reciting the prayers.
Nomenclature and etymology 
Prayer wheel or Mani wheel (Tibetan: མ་ནི་ཆོས་འཁོར་, Wylie: mani-chos-'khor). The Tibetan term is a contraction: "Mani" itself is a contraction of Sanskrit cintamani; "chos" is Tibetan for Dharma; and "khor" or "khorlo" means chakrano
The earliest recorded prayer wheels were written of by a Chinese pilgrim around 400 C.E. in Ladakh. The concept of the prayer wheel is a physical manifestation of the phrase "turning the wheel of Dharma," which describes the way in which the Buddha taught. Prayer Wheels originated from ‘The School of Shakyamuni sutra, volume 3 – pagoda and temple’ which states that, “those who set up the place for worship, use the knowledge to propagate the dharma to common people, should there be any man or woman who are illiterate and unable to read the sutra, they should then set up the prayer wheel to facilitate those illiterate to chant the sutra, and the effect is the same as reading the sutra”
According to the lineage texts on prayer wheels, prayer wheels are used to accumulate wisdom and merit (good karma) and to purify negativities (bad karma). In Buddhism, Buddhas and Bodhisattvas have created a variety of skillful means (upaya) to help bring practitioners ever closer to realizing enlightenment. The idea of spinning mantras relates to numerous Tantric practices whereby the Tantric practitioner visualizes mantras revolving around the nadis and especially around the meridian chakras such as the heart and crown. Therefore, prayer wheels are a visual aid for developing one's capacity for these types of Tantric visualizations. The spiritual method for those practicing with a prayer wheel is very specific (with slight variations according to different Buddhist sects). The practitioner most often spins the wheel clockwise, as the direction in which the mantras are written is that of the movement of the sun across the sky. On rare occasions, advanced Tantric practitioners such as Senge Dongma, the Lion-Faced Dakini, spin prayer wheels counterclockwise to manifest a more wrathful protective energy. As the practitioner turns the wheel, it is best to focus the mind and repeat the Om Mani Padme Hum mantra. Not only does this increase the merit earned by the wheel's use, but it is a mind-stabilization technique that trains the mind while the body is in motion. Intoning the mani mantra with mindfulness and the "Bodhicitta" motivation dramatically enhances the effects of the prayer wheel. However, it is said that even turning it while distracted has benefits and merits, and it is stated in the lineage text that even insects that cross a prayer wheel's shadow will get some benefit. Each revolution is as meritorious as reading the inscription aloud as many times as it is written on the scroll, and this means that the more Om Mani Padme Hum mantras that are inside a prayer wheel, the more powerful it is. It is best to turn the wheel with a gentle rhythm and not too fast or frantically. While turning smoothly, one keeps in mind the motivation and spirit of compassion and bodhichitta (the noble mind that aspires to full enlightenment for the benefit of all beings). The benefits attributed to the practice of turning the wheel are vast. Not only does it help wisdom, compassion and bodhichitta arise in the practitioner, it also enhances siddhis (spiritual powers such as clairvoyance, precognition, reading others thoughts, etc.). The practitioner can repeat the mantra as many times as possible during the turning of the wheel, stabilizing a calm, meditative mind. At the end of a practice session, there is a Tibetan Buddhist tradition of dedicating any accumulated merits that one may have gathered during practice to the benefit of all sentient beings. Then Om Ah Hum 3 times. This is customary with Tibetans upon completing any Buddhist practice, including the practice of the prayer wheel.
Thubten Zopa Rinpoche has commented that installing a prayer wheel has the capacity to completely transform a place, which becomes "...peaceful, pleasant, and conducive to the mind." Simply touching a prayer wheel is said to bring great purification to negative karmas and obscurations.
Mani wheel 
The Mani wheel, or the hand prayer wheel, is a cylindrical body mounted on a wooden or metal handle. The cylinder itself is weighted down with a cord or chain allowing it to be spun by a slight rotation of the wrist along with the mantra it contains.
Water wheels 
This type of prayer wheel is simply a prayer wheel that is turned by flowing water. The water that is touched by the wheel is said to become blessed and carries its purifying power into all life forms in the oceans and lakes that it feeds into.
Fire wheel 
This wheel is turned by the heat of a candle or electric light. The light emitted from the prayer wheel then purifies the negative karmas of the living beings it touches.
Wind wheel 
This type of wheel is turned by wind. The wind that touches the prayer wheel helps alleviate the negative karma of those it touches.
Stationary prayer wheels 
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.
Electric dharma wheels 
Some prayer wheels are powered by electric motors. "Thardo Khorlo," as these electric wheels are sometimes known, contain one thousand copies of the mantra of Chenrezig and many copies of other mantras. The Thardo Khorlo can be accompanied by lights and music if one so chooses. However, Lama Zopa Rinpoche has said, "The merit of turning an electric prayer wheel goes to the electric company. This is why I prefer practitioners to use their own 'right energy' to turn a prayer wheel".
