Once Kaatyaayan had cherished a keen desire to have Shakti born as his daughter. The goddess acceded to his request. Meanwhile, army of the powerful demon Mahishaasur, who could only be killed by a warrior Goddess, had reached Swarg to overthrow the gods from their abode. The trinity of gods – Brahmaa, Vishnu and Shiv, got infuriated and they created the goddess Durgaa, who was a culmination of the powers of all deities. Sage Kaatyaayan had the first privilege to worship her, so she was also named Kaatyaayanee.
