One of the nine forms of Goddess Durga, who is worshipped on the third day of Navratri is Goddess Chandraghanta.
The Goddess wears the crescent on her head which resembles a moon and hence her name is Chandraghanta.
Seated on a tiger, Goddess Chandraghanta is depicted with dushabhuja or ten hands.
She is one of the most ferocious forms of Goddess Durga and is well equipped for a war (if a need arises) for the welfare of humanity. Her devotees seek her blessings for courage, strength and bravery.
