Durga created a large army from her breath to fight Mahisha's army and then fought with Mahisha who came in the form of a Buffalo. As he struggled to set himself from the Buffalo form she killed him with her sword delivering the earth and heavens of the Burden called Mahishasura. There after Durga Devi then called Mahishashur Mardini Mata.
