A vajra is a weapon used as a ritual object to symbolize both the properties of a diamond (indestructibility) and a thunderbolt (irresistible force).
It is used to psychicly clean a room or heal a desease.
It is used for protection from negative energies.
According to the Indian mythology, vajra is considered as one of the most powerful weapons in the universe. The use of the vajra as a symbolic and ritual tool spread from India along with indian religion and culture to other parts of Asia.
