Bhairav Raksha Kavach is associated with the Kal Bhairava
form of Mahadev Shiva. The common belief is that those people wearing the
amulet will be protected and blessed by Bhairava. It protects people from the
fear of ghosts and darkness.
Bhairav Raksha Kavach is also widely used by people who
believe that their progress is hampered by mantras and tantras of their
enemies. The belief is that the person who wears the kavach is invisible to
enemy mantras and tantras.
It is also worn for good health, to wipe out thoughts of
failure and to overcome lethargy.
