Five Unrelated Civilizations Described the Same Bridge to the Afterlife

Five separate civilizations — Persian, Islamic, Christian, Chinese, and Norse — describe the dead crossing a bridge into the afterlife. Four of them agree on the one detail that should never have traveled: the bridge changes width. Wide for the good. Thin as a razor for the guilty. The Zoroastrians even gave it a number. This video walks across all five crossings — from the Chinvat Bridge in ancient Persia, to the Sirāt over Hell in Islam, to Simon Marmion's spiked bridge in the Getty Museum's Ms. 30, to the Naihe Bridge in the Chinese underworld — and asks the honest question: is this just a metaphor the human mind reaches for, or the same instruction surfacing in places that never compared notes?
