Durga is an incarnation of Devi or the Mother Goddess, a unified symbol of all divine forces. Durga is the wife of Lord Shiva. Durga is also another form of Uma or Parvati.
The Hindu Goddess Durga manifested when evil forces threatened the very existence of the Gods. To destroy these demons, all Gods offered radiance to her creation and each formed part of Durga’s body. Durga also obtained very powerful weapons such as the Sudarsan Chakra / disk from Lord Vishnu and the Trishul / trident from Lord Shiva.
The name Durga in Sanskrit means “invincible”. Durga killed the powerful demon Mahishasura & all his great commanders.
