Chhinnamasta Worship is mainly performed for getting a son, to remove poverty, to gain wisdom, to destroy enemies and to be a poet. Chhinnamasta is associated with the concept of self-sacrifice as well as the awakening of Kundalini. In a story from the Shakta Maha-Bhagavata Purana, which narrates the creation of all Mahavidyas including Chhinnamasta, Sati, the daughter of Daksha and the first wife of the god Shiva, feels insulted that she and Shiva are not invited to Daksha's yagna ("fire sacrifice") and insists on going there, despite Shiva's protests. After futile attempts to convince Shiva, the enraged Sati assumes a fierce form, transforming into the Mahavidyas, who surround Shiva from the ten cardinal directions. Chhinnamasta stands to the right of Shiva in the west.
