According to Legend, Goddess Parvathi killed a ferocious demon called Kamsasuran who lived here and attempted to become powerful through his penance. Devi along with the help of Veerabadra, Ganesha and Shiva initially made him dumb and he came to be called Mookasuran (Mooka means dumb). Later the goddess killed him and called as Mookambika thereafter.
