The seventh day is dedicated to Maa Kaalratri. In this form, She is the dark complexioned avatar of Maa Parvati that she attains by liberating the golden outer sheath. She is the destroyer of evil and negativity.
Mantra: Om Aim Hlim Klim Chamundayai Vichchai; Ekveni Japakarnapoora Nagna Kharasthita; Lamboshthi Karnikakarni Tailabhyaktasharirini; Vampadollasallohalatakantakabhooshna; Vardhanmoordhwaja Krishna Kalratrirbhayankari.
Translation: May the Bhayankari Maa Durga who is with long lips, riding a donkey, shining in various hues, looks formidable because of the halo of Devi’s luster and is adorned with multi coloured ornaments remove my darkness of ignorance.
