Bhairava originates through the word bhīru, which implies "fearsome". Bhairava signifies "terribly fearsome type". It is actually often known as just one who destroys dread or a single who is beyond panic. Just one interpretation is always that he protects his devotees from dreadful enemies, greed, lust, and anger. https://www.youtube.com/watch?v=S2iLMNuDYc0
