Fire in Zoroastrianism is not worshipped — it is the supreme witness. Atar is the son of Ahura Mazda, the visible form of Asha in the material world. Prayers are offered in the presence of fire because fire cannot lie: it illuminates, purifies, and consumes. It does not compromise. Hex 30 (The Clinging) is fire's nature: Lí, radiance that must cling to something to shine. Fire without fuel dies. Truth without a vessel is invisible. Hex 50 (The Caldron) is fire as transformative agent: the sacred vessel where offerings are cooked, where raw becomes nourishing, where matter is transmuted through heat. The Zoroastrian fire temple (Atash Behram) maintains a fire that must never go out — this is Hex 30's perseverance: 'Care of the cow brings good fortune.' Tend the flame. Do not let it die.
