At death, every soul crosses the Chinvat Bridge. For the righteous, the bridge widens to a broad highway; for the wicked, it narrows to a razor's edge and they fall into the House of the Lie. The bridge does not judge — it reveals. It separates what you are from what you pretended to be. Hex 21 (Biting Through) is judgment that cuts through obstruction: thunder and lightning, fire and thunder, the law court that discriminates. Hex 10 (Treading) is the act of crossing itself — treading on the tail of the tiger, walking carefully where the stakes are absolute. 'Treading upon the tail of the tiger. It does not bite the man.' The righteous cross safely not because the bridge is safe but because they have already become what the bridge tests for.
