A fire temple in Zoroastrianism is the place of worship for Zoroastrians, often called dar-e mehr. In the Zoroastrian religion, fire, together with clean water, are agents of ritual purity. Clean, white "ash for the purification ceremonies is regarded as the basis of ritual life," which "are essentially the rites proper to the tending of a domestic fire, for the temple [fire] is that of the hearth fire raised to a new solemnity".
