Are Kali and Durga the same?

Goddess Durga is also referred to as a warrior Goddess. She is believed to have killed asuras. Similarly, Goddess Kali is also known for her power to destroy wrongdoers and asuras transcending death. Both Goddess Kali and Durga stayed in their domestic ambit and were celebrated as mother figures. As per mythology, when Goddess Durga became very angry at the misdeeds of the asuras, Goddess Kali was born from her forehead. Goddess Kali went on a destructive rampage killing demons and asuras. She shed her fair skin and took on the fierce avatar of Kali, and as such, she is also referred to as Kaushika or the Sheath. Thus, Goddess Kali is an incarnation of Goddess Durga.
