The asura Darika was said to have a very chaste wife, Manodari, who had in her possession a special mantra that would keep her husband invincible, and thus her marriage forever safe. Darika used his newfound invincibility to torment the lokas and usurp the kingdom of the Devas. When Lord Shiva came to know about the misdeeds of demon Darika, he opened his fiery third eye and the massive ferocious form of Bhadrakali emerged (In this incarnation, the Goddess was not his wife, but her daughter.) Shiva ordered Bhadrakali to destroy Darika, with a Vetala as her vehicle.
