In Indic religions, a homa (Sanskrit: होम) also known as havan, is a fire ritual performed on special occasions by a Hindu priest usually for a homeowner ("grihastha": one possessing a home). The grihasth keeps different kinds of fire including one to cook food, heat a home, amongst other uses; therefore, a Yajna offering is made directly into the fire. A homa is sometimes called a "sacrifice ritual" because the fire destroys the offering, but a homa is more accurately a "votive ritual". The fire is the agent, and the offerings include those that are material and symbolic such as grains, ghee, milk, incense and seeds. It is rooted in the Vedic religion, and was adopted in ancient times by Buddhism and Jainism. The practice spread from India to Central Asia, East Asia and Southeast Asia. Homa rituals remain an important part of many Hindu ceremonies, and variations of homa continue to be practiced in current-day Buddhism, particularly in parts of Tibet and Japan. It is also found in modern Jainism. It is also practiced by Nihang Sikhs. A homa is also called yajna in Hinduism, sometimes for larger public fire rituals, or jajnavidhana or goma in Buddhism. In modern times, a homa tends to be a private ritual around a symbolic fire, such as those observed at a wedding. The Sanskrit word homa (होम) is from the root hu, which refers to "pouring into fire, offer, sacrifice". Homa traditions are found all across Asia, from Samarkand to Japan, over a 3000-year history. A homa, in all its Asian variations, is a ceremonial ritual that offers food to fire and is ultimately linked to the traditions contained in the Vedic religion. The tradition reflects a reverence for fire and cooked food (pākayajña) that developed in Asia, and the Brahmana layers of the Vedas are the earliest records of this ritual reverence. The yajñā or fire sacrifice became a distinct feature of the early śruti rituals. A śrauta ritual is a form of quid pro quo where through the fire ritual, a sacrificer offered something to the gods and goddesses, and the sacrificer expected something in return.
