Is the term for a sacred purifying ritual in Hinduism that involves a fire ceremony. It is a ritual of sacrifice made to the fire god Agni. After lighting a Havan Kund (sacrificial fire), objects such as fruits, honey, or wooden goods are put into the sacred fire. If there are any spirits that are evil around you or even inside you they get burned off in the sacred fire. It is believed that this sacrifice will bring health, happiness, luck and prosperity.

Person doing havan should sit on the south (facing north) and head of household should sit in the west facing east. Other attendees can sit anywhere. Put some water in the 4 bowls and some samagri in the 3 plates for attendees use during the Havan. The 4th is the main plate used below. Set up the diya by putting some Ghi and the cotton wick in it. Put some halwa (or other sweet stuff) in plate.
