In the various sects of Hinduism, the agni-hotra, or "fire
ceremony", remains a major keystone in rites of passage. At times such as
first intiation (diksha), marriage, etc., whilst in the temple, a
priest (pujari) will chant mantras, pouring ladles of
ghee into a sacrificial fire, whilst the followers do the same.
Karma, it is said, is like a seed or grain that will later fructify
into activity. The act of throwing grains in the ceremonial fire symbolises
the burning off of one's karma in the fire of knowledge
(vidya) and devotion (bhakti).
