According to Hindu mythology, Shiva once spotted his consort, Parvati, leave their bed in the middle of the night, and return only before sunrise. When he questioned her regarding this, his wife was puzzled, and informed him that she had not left his side all night. When Shiva observed this happening once more, he proceeded to follow her from Kailasa to a forest, and witnessed that she had assumed the terrible form of Kali, digging up corpses, with the intention of consuming them. Determined to stop her, he dug a hole in the forest path. When Kali fell within the hole and saw Shiva, she was filled with remorse for her actions, and promised Shiva that she would end this morbid pursuit. She also told Shiva that she would leave behind her terrible form within the hole, and return to him as a dutiful wife. The shakti that was left behind would become her form of Kateri Maa (काटेरी माता), a benevolent goddess who destroys sicknesses, and shields her adherents.
