Vajra is a Sanskrit word meaning both "thunderbolt" and "diamond." It is a weapon and symbol representing firmness of spirit and spiritual power. In Hinduism and Buddhism, the vajra is associated with Indra and various bodhisattvas, symbolizing the indestructible nature of enlightenment. It is like the divine equivalent of a flash drive containing all the strength and unshakeable resolve you need when things get tough. Metaphorically, it represents sudden insight.
