and temple’ which states that: Another theory, which seems more plausible, is that rotating mantras relate to numerous yogic or Tantric practices whereby the Tantric practitioner visualizes the mantra revolving around his or her nadis and especially around the meridian chakras such as the heart and crown. The prayer wheels are a visual aid for developing the capacity for these types of Tantric visualizations. Practice 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.

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,
