What is the name of Indra's weapon?

Indra’s weapon is the vajra, a thunderbolt associated with irresistible force.

In Vedic mythology, Indra wields the vajra as the chief weapon of the devas. The Rigveda describes him using it to defeat Vritra, a serpent-like asura who obstructed the waters. By overcoming Vritra, Indra releases the life-giving waters and restores cosmic order. The weapon is traditionally connected with Tvastr, the divine craftsman who makes instruments for the gods.

The vajra’s symbolism combines the power of a thunderbolt with the indestructibility of a diamond. This dual meaning helped the object remain important beyond early Hindu mythology. In Buddhism, especially Tibetan Buddhism, the vajra becomes a ritual scepter symbolizing firmness, clarity, and spiritual power; it is often paired with a bell.

A common mix-up is treating every famous divine weapon as Indra’s. Trishula belongs primarily to Shiva, while the Brahmastra is a destructive celestial missile associated with Brahma and epic heroes. Shakti can mean divine power and also refers to certain spear-like weapons, but the canonical weapon of Indra is the vajra.
