This comes in Copper, Brass & Gold painted which is of 4 inch Stupa Prayer Wheel. Inside the stupa you can see the Prayer Wheel which has Om Mani Padme Hung engraved on it. It is studded with Turquoise and Coral. It is 4 inches high and runs on electricity.
It is suggested that one recites the six syllable mantra - OM MANI PADME HUM - while turning the Mani wheel. In the translation of a text by the Fourth Panchen Lama, 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.” In the same text Shakyamuni Buddha says that "turning the prayer wheel once is better than having done one, seven, or nine years of retreat" The prayer wheel is a very powerful merit field; one accumulates extensive merit and purifies obstacles.
