The Vajra (Sanskrit: वज्र) or Dorje (Tib.: རྡོ་རྗེ།), literally . "Thunderbolt") is a legendary and ritual weapon, symbolizing the properties of diamond's indestructibility and thunderbolt's irresistible force.
The vajra is a type of club with a ribbed spherical head. The ribs may meet in a ball-shaped top, or they may be separate and end in sharp points with which to stab. The vajra is the weapon of Indra, the Vedic king of the devas and heaven. It is used symbolically by the dharmic traditions of Hinduism, Buddhism, and Jainism, often to represent firmness of spirit and spiritual power.
This graceful Vajra adorns the most exquisite altar.
