Also known as: kongou-sho (金剛杵)

A mystical indestructible weapon in Buddhism and Hinduism which destroys ignorance. In Hindu mythology, this weapon was made out of the spine of the sage Dadhichi, who sacrificed himself so that this weapon could be created to kill Vitrasur, who had conquered heaven and terrorized gods.

In tantric rituals, the vajra, held in the right hand, symbolizes the male principle while the bell, held in the left hand, symbolizes the female principle; their interaction leads to enlightenment.
