Kalabhairavashtakam - Eight Verses on Kalabhairava By Shankara Bhagavadpaada

This hymn praises the lord kālabhairava who is the guardian of kāshi as the supreme god who is non different to Shiva and non different to atman our true self. He who is the creator, protector, destroyer of the whole world.

He is the giver of wisdom and liberation, destroyer of all evil qualities.

This hymn was sung by achārya ādi shankara bhagavadpāda in the holy shrine of kāshi.
