Chinvat Bridge

The Chinvat Bridge, Avestan for "bridge of the separator," is the hinge of the Zoroastrian afterlife. The prophet's own Gathas already invoke it: the righteous will be led across, while the followers of the Lie are denounced by their own souls at its head. As the Pahlavi books elaborate, the soul lingers near the body for three nights and comes to the bridge at the fourth dawn. The span runs from the Peak of Judgment, Chakad-i Daitik at the center of the world, to the Alborz range, over the gulf of hell; at its head sit Mithra, Sraosha, and Rashnu, the last holding golden scales that tip for no one, weighing every thought, word, and deed of the life just ended.

The judgment works through the bridge itself: for a soul whose good deeds prevail, the way broadens to nine spear-lengths, and a beautiful, fragrant maiden comes to meet him — his own daena, the embodiment of his faith and conduct — leading him up three steps into paradise. For the wicked the bridge turns on edge, thin as a razor, the daena appears as a hideous crone, and the soul plunges to a hell exactly as deep as its guilt. The ninth-century Pahlavi visionary text Arda Wiraz Namag recounts how the righteous Wiraz crossed the bridge in spirit under Sraosha's escort and toured the rewards and torments level by level, a book often set beside Dante's Divine Comedy. The image also passed into the later Islamic tradition of the Sirat bridge.
