Introduction to prayer wheels: Prayer wheels, also known as "Mani" prayer wheels, are related to the six-character mantra. Tibetan Buddhism believes that the more you chant the six-character mantra, the more you show your devotion to the Buddha 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" sutra scrolls in the tubes, and turn them by hand. Each rotation is equivalent to chanting the sutra once. (Prayer wheel in Xiagui Village)
