Introduction to prayer wheels: Prayer wheels, also known as "Mani" prayer wheels (Maņi in Sanskrit, meaning wish-fulfilling pearls in Chinese), are related to the six-character mantra (the six-character Great Ming Mantra). Tibetan Buddhism believes that, The more you recite the six-character mantra, the more pious you are to the Buddha and Bodhisattvas, and you can escape the suffering of reincarnation. Therefore, in addition to reciting orally, people also make "Mani" prayer tubes, put the "Six-Character Great Ming Mantra" scripture scrolls in the prayer tubes, and turn them by hand. The Tibetan people put the scriptures in the prayer tubes and rotate them every time. One time is equivalent to reciting the sutra once, which means reciting the "Six-Character Great Ming Mantra" hundreds or thousands of times. Some people also use water power and lamp heat to make water-turning mani tubes and lamp-turning mani tubes, and natural forces recite the "Six-syllable Great Ming Mantra" on behalf of people. In front of temples of all sizes in Tibetan areas, rows of prayer wheels are lined up, with handles at the lower end that can be used to push and shake. Believers often go to temples to push the prayer wheels to rotate, which is called prayer wheels.
