According to the Hindu mythology there is a story behind the origin or Chandraghanta which is depicted below:
After Lord Shiva gave Parvati his word that he would not marry any woman, her sufferings overwhelmed him so much that he gave up, followed by a tearful reunion and then agrees to marry her. Soon, the joyous moment of Parvati's life comes. Shiva brings a procession of gods, mortals, ghosts, ghouls, goblins, sages, ascetics, Aghoris and Shivaganas to the gates of King Himavan's palace to take away his bride Parvati, on the occasion of his remarriage. Shiva arrives at King Himavan's palace in a terrorizing form and Parvati's mother Maina Devi faints in terror. Parvati appears to Shiva and sees his fearsome form, so to save her parents and other family members she transforms herself into Goddess Chandraghanta.
Chandraghanta persuaded Shiva to re-appear in a charming form. On listening to the Goddess, Shiva appears as a prince decorated with countless jewels. Parvati revived her mother, father and friends then Shiva and Parvati get married and made promises to one another
