Diamond-pounder
diamond-pounder 金剛杵 (Skt vajra; Jpn kongo-sho )
Originally a kind of weapon used in ancient India.
It is so called because of its legendary hardness—it was thought capable of destroying any other weapon, as a diamond is impervious to all other materials.
In the rituals of Esoteric Buddhism, the diamond-pounder symbolizes the firm resolve to attain enlightenment, which can destroy all illusions.
This diamond-pounder, or vajra, usually made of iron or copper, is slender in shape with pointed ends.
There are usually three types: a single-armed, a three-pronged, and a five-pronged diamond-pounder.
Among these, the three-pronged pounder represents the three mysteries, and the five-pronged pounder, the five kinds of wisdom possessed by the one Buddha Mahavairochana or by five Buddhas, respectively.
