The Hearth Fire — Atash-i Dadgah, Domestic Sacred Flame

The Atash-i Dadgah ('Fire of the Appointed Place') is the lowest of the three grades of sacred fire in Zoroastrian practice, burning in homes and local dar-i mihrs (fire temples). Unlike the Atash Behram (highest grade, consecrated from sixteen fires) and the Atash-i Adaran (middle grade, consecrated from four professional fires), the Dadgah requires no elaborate investiture — any ritually pure fire may serve. As described in the Vendidad's purity codes, this domestic flame is tended as a daily act of devotion, linking household life directly to the cosmic function of Atar as Asha's visible witness. The Atash Niyayesh prayer, recited in the fire's presence, addresses Atar as the intermediary through which offerings of fragrant wood and prayers ascend to Ahura Mazda.
