Agni is the God of Fire and is one of the most prominent of the deities of the Vedas. With the exception of Lord Indra, more hymns are addressed to him than to any other deity.
The worshippers of Agni prosper, attain wealth, and live long. He watches with a thousand eyes over the man who brings him food, and nourishes him with oblations. No mortal enemy can by any wondrous power gain the mastery over him who sacrifices to this god. He also confers and is the guardian of immortality. In a funeral hymn, Agni is asked to warm with his heat the unborn (immortal) part of the deceased, and in his auspicious form to carry it to the world of the righteous.
He carries men across calamities, as a ship over the sea. He commands all the riches in earth and heaven; hence he is invoked for riches, food, deliverance, and in fact all temporal good. He is also prayed to as the forgiver of sins that may have been committed through folly. All gods are said to be comprehended in him; he surrounds them as the circumference of a wheel does the spokes.
The Origin & Appearance of Agni
In pictures, he is represented as a red man, having three legs and seven arms, dark eyes, eyebrows and hair. He rides on a ram, wears a poita (Brahmanical thread), and a garland of fruit. Flames of fire issue from his mouth, and seven streams of glory radiate from his body.
