Etymology

The word Aithal derives from a prerequisite vedic ritual of securing and maintaining the three fires. Ahita anala yasya sah, is an ahitanala, which essentially means one who has secured and has been maintaining the three fires required for an agnichayanam. The Apabhramsa form of this word became aithala. As one of the members of a vedic group, Aithalas have co-existed with Vaishnavas for a long time. Aithal comes from the Sanskrit words ahiti which means placing and anala meaning fire. The meaning is similar to the word agnihotra.
