Durga Maa is the principal form of the Mother Goddess in Hinduism. She is pure energy (referred to as “Shakti” in Sanskrit and Hindu religious context). Being innately formless (known as Adi Parashakti), she manifests herself within the gods and demi-gods so that she may fulfill the tasks of the universe via them. At times of distress, such as when Mahishasura terrorised the universe, she manifests herself in divine form to protect the world.
