This symbol which is a cauldron type container with flames coming out the top, is a primary symbol for Zoroastrianism. The dichotomy of atar is in its symbolism it is both invisible and visible fire and unburning and burning fire. It is the visible presence of Ahura Mazda, the one god of Zoroastrianism. He is the creator of Asha – truth and upholds truth.
Zoroaster, an Iranian prophet, was led to Ahura Mazda when Zoroaster was thirty years old. Ahura Mazda taught Zoroaster the basic principles of the “Good Religion” later known as Zoroastrianism.
Zoroastrianism prayers are to be said in the presence of light, such as fire. The fire is purified 1,128 times a year. They pray toward the atar or their hearth to better achieve righteousness and virtue they are striving for. Atar is considered a medium through which judgment is passed. Atar is also the light of revelation by which Zoroaster becomes a prophet. Atar radiates the essence of Ahura Mazda from which wisdom and insight permeate the universe. Later texts have atar being the son of Ahura Mazda.
