Virtually every civilization has worshiped a sun god but in Bihar, it is the setting sun that is worshiped.
Photographer Praful Rao documented the Chatt Puja, which is when the Bihari community in Kalimpong congregate in an open area much before dawn to worship the sun. Women bedecked in colorful saris, along with their husbands carrying puja material in baskets, arrive to the area much before sunrise. It is they who perform the puja.
