Bhairava originates from the phrase bhīru, which means "fearsome". Bhairava suggests "terribly fearsome type". It is actually often known as a person who destroys dread or a person who's beyond dread. One interpretation is the fact he protects his devotees from dreadful enemies, greed, lust, and anger.
