Ganesh Chaturthi is the celebration of the birthday of the elephant-headed Hindu god Ganesh. The festival involves the buying and building of Ganesh statues, decorating and worshiping them at home and then at the end of the festival, immersing them in water. These were the small ones lined up around a temple on the corner just down the street from me. Families will buy and display small clay ones at home or give them to the temples as here.
