in Oriental mythology, is the name of the bridge over the gulf which separates, according to Zoroaster's teaching, the realm of light' from that of darkness. The spirits of the dead are obliged to confess their sins upon this bridge, and according as these are pardonable or otherwise, they are admitted to the realm of light or hurled into the yawning gulf.. It is said there is a place in Thibet,. near the spring of Brahmaputra, showing what this doctrine is designed to express. The pilgrims to this sacred' place are transported across an abyss on .a scale. Suspended in midair, they are obliged to confess their sins to the bonzes; Any hesitancy, even the slightest stammering, may cause the bonzes to remove the balance, and the unfortunate one is hurled into the depth below.
