Prayer-wheels

or CYLINDERS, used in Lama worship, consist of a long strip of paper, inscribed with charms and prayers and wound round a cylinder which revolves by a handle. When the cylinder is set in motion the paper revolves and the prayers are supposed to operate. Not only are they swung by the hand, but ithey are sometimes set revolving in a stream or hung in the wind. Hackmann: Buddhism as a Beligion.
