The Agnihotra involves fire, and the term refers to the ritual of keeping fire at home, and in some cases making "sacrificial offerings" such as milk and seeds to this fire.  The Srauta texts state that it is the duty of man to perform Agnihotra . A wide range of Agnihotra procedures are found in the Brahmana layer of the Vedas, ranging from the most common simple keeping of sacred fire and its symbolism, to more complicated procedures for the expiation of guilt, to rituals claimed to grant immortality to the performer.  According to the Jaiminiya Brahmana , for example, an Agnihotra sacrifice frees the performer from evil and death.  In contrast, states the Shatapatha Brahmana, Agnihotra is a symbolic reminder and equivalent to the Sun, where the fire keeper is reminded of the heat that creates life, the fire in beings, the heat in the womb behind the cycle of life.
