A story from the "Shakta Maha-Bhagavata Purana" and the "Brihaddharma Purana" (13th century) narrates the creation of all Mahavidyas, including Chhinnamasta. The story is as follows: Sati, the daughter of Daksha, is the first wife of the god Shiva. When she and Shiva are not invited to the fire sacrifice organized by her father, she is insulted and insists on attending, despite Shiva's protests. After futile attempts to convince Shiva to grant his consent for her to attend, the enraged Sati assumes a fierce form, transforming into the Mahavidyas, who surround Shiva from the ten cardinal directions. As per the "Shakta Maha-bhagavata Purana", Chhinnamasta stands to the right of Shiva, interpreted as the east or the west; the "Brihaddharma Purana" describes her as appearing to the rear of Shiva in the west.
