Maa Durga is the most popular incarnation of Devi and one of the main forms of the Goddess Shakti.
Durga is the original manifested form of Mother Adi-Parashakti. Durga is Adi-Parashakti herself. The Devi Gita, declares her to be the greatest Goddess. Thus, she is considered the supreme goddess and primary deity in Shaktism, occupying a place similar to Lord Krishna in Vaishnavism. According to Skanda Purana, the goddess Parvati accounted the name "Durga" after she killed the demon Durgamaasura. Goddess Parvati is considered to be the complete incarnation of Adi Parashakti or Goddess Durga, with all other goddesses being her incarnations or manifestations. Adi Parashakti or Mahadevi, the supreme power, is called Durga Shakti as per Devi-Mahatmya. Adi Parashakti or Devi Durga is a Hindu concept of the Ultimate Shakti or Mahashakti, the ultimate power inherent in all Creation. This is especially prevalent in the Shakta denomination within Hinduism, which worships the Goddess Devi in all her manifestations.
