Hand painted prayer wheels made at the Sange AKA Wutun Monasteries in Eastern Tibet in the Amdo region.
Prayer Wheels are are a manifestation of the Compassion Buddha's holy speech. Turning the prayer wheel with bodhichitta motivation while reciting the 6-syllable mantra will allow "one to collect more extensive merit to quickly achieve enlightenment than an arhat who abides for many years in the blissfull state of peace for oneself alone." (Lama tubten Zopa Rinpoche) "..in the text by the 4th Panchen Lama, I translated a section in which Amitabha Buddha says, 'Anyone who recites the six syllables while turning the Dharma wheel at the same time is equal in fortune to the Thousand Buddhas,' and in which Shakyamuni Buddha says that turning the prayer wheel once is better than having done one, seven, or nine years of retreat." (Lama Thubten Zopa Rinpoche from the forward to WHEEL OF GREAT COMPASSION~ The Practice of the Prayer Wheel in Tibetan Buddhism by Lorne Ladner.
