Chhath Puja is a four-day Hindu festival dedicated to the worship of the Sun God (Surya) and Chhatti Mai (Goddess of Power). During the festival, devotees gather at rivers and ponds to sing folk songs, take dips in the water, and pray to the Sun God with offerings to thank him for sustaining life on Earth. It is considered a festival of forgiveness and compassion where cultural bonds are made through the sharing of fruits and sweets.
