The Gao is used within this tradition as an amulet – a ritualistic object believed to provide protection from evil. This Gao is made of brass, with the addition of a silver buddha placed in the window. Within this is a scroll of a hand written prayer. The scroll would have been prepared and blessed by a Buddhist priest. Also inside may be herbs, stones and other objects believed to have protective powers.
The Gao is usually worn around the neck and hung close to the heart. It’s like a portable shrine!
