In Hinduism, Durga is the principle goddess who influences creation and preservation. Worship and celebration of Durga occurs during Basanti puja (observed during spring in West Bengal) and Durga puja (observed widely in India during autumn). Basanti puja is not as popular as Durga puja, but follows the same rituals as the autumnal season celebration, in observance of gratefulness to Durga for the spring season.
Basanti puja is usually celebrated for nine or 10 days. Festivities include worship, music, fireworks and the creation of large statues made from clay and natural elements (straw, grass, bamboo, etc.) that are returned to a river on the fourth night of the festival to dissolve back into the earth.
