Havanam (also Havana, Havan) is the term for a sacred purifying ritual (yajna) 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.
