In Hinduism, the worship is done with a variety of items. The items are offered to the deities in the form of Puja. Puja items include flowers, incense sticks, a lamp, a candle, water, fruits and sweets. Some people might have elaborate Puja ceremonies at home or in temples but this article will focus on what you need to offer your deities during Diwali and Navratri. The most important item for both Diwali and Navratri is an earthen pot called a "kalash" that holds water for the offering.
