Navratri is a nine-day festival celebrated in India to worship the nine forms of the goddess Durga. It is celebrated twice a year, once in the month of Chaitra (March-April) and the other in the month of Ashwin (September-October). Navratri Puja is performed during these nine days to seek blessings and protection from the goddess Durga.

Here are the steps to perform Navratri Puja:
