Mahalaya 2021: As per the Hindu Calendar, Mahalaya is celebrated by the devotees of Maa Durga a week before Durga Puja celebrations begin. Mahalaya is marked on the last day of Pitru Paksha which is being observed today, on October 6 this year. It is celebrated in the states of Karnataka, Odisha, Tripura, and West Bengal. It is believed in the Hindu Mythology that Goddess Durga was created on this day by Brahma, Vishnu, and Maheswar to defeat the demon king Mahishasura. Therefore, devotees mark this day as the arrival of Goddess Durga to Earth from Kailash Parvat with her divine powers. On the day of Mahalaya, the sculptors only make Goddess Durga’s eyes and fill colours in them. They also perform a special puja before this.
