Homa’s & pooja’s

Homa is Sanskrit for a ritual, wherein an oblation or any religious offering is made into 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, clarified butter, milk, incense and seeds.

It is rooted in the Vedic religion and was adopted in ancient times by Buddhisam 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

A homa ritual is known by alternative names, such as yajna in Hinduism which sometimes means larger public fire rituals, or jajnavidhana or goma in Buddhism. In modern times, a homa or havana (also havan) tends to be a private ritual around a symbolic fire, such as those observed at a wedding.
