About Vajra
The Vajra is a literal ritual object associated with Tibetan Buddhism, also called by its Tibetan name, Dorje. It is the symbol of the Vajrayana school of Buddhism, which is the tantric branch that contains rituals said to allow a follower to achieve enlightenment in a single lifetime, in a thunderbolt flash of indestructible clarity.
The vajra objects usually are made of bronze, vary in size, and have three, five or nine spokes that usually close at each end in a lotus shape. The number of spokes and the way they meet at the ends have numerous symbolic meanings.
