Homa (also known as "homam" or "havan") is a Sanskrit word which refers to any ritual in which making offerings into a consecrated fire is the primary action. At present, the words "homa/homam" and "havan" are interchangeable with the word "Yagna."

Yagya is a ritual of sacrifice derived from the practice of Vedic times. It is performed to please the gods or to attain certain wishes. An essential element is the sacrificial fire - the divine Agni - into which oblations are poured, as everything that is offered into the fire is believed to reach the gods. A Vedic (Śrauta) yajna is typically performed by an "adhvaryu" priest reciting Vedic verses. Usually, there will be one or three fires in the centre of the offering ground. Among the items offered as oblations in the yajna include large quantities of ghee, milk, grains, cakes or soma. The duration of a yajna depends on the type; some can last a few minutes, hours or days and some even last for years. Some yajnas are performed privately, others with a large number of people in attendance.
