The Weighing of the Heart (wezbet ib) is the central judgment scene of the Egyptian afterlife, depicted most famously in the Papyrus of Ani and codified throughout the Book of the Dead, particularly in Spell 125. In the Hall of Two Truths (Maaty), Anubis places the deceased's heart-ib on one pan of the great scales and the feather of Ma'at on the other, while Thoth records the outcome and the devourer Ammit waits below. The deceased must recite the Negative Confessions before forty-two assessor deities, declaring freedom from isfet — and if the heart balances against the feather, the ba is declared maa-kheru ('true of voice') and admitted to the Field of Reeds. This scene encodes the Egyptian moral architecture: the heart is not weighed against a law code but against cosmic order itself, and only a life lived in alignment with ma'at produces a heart light enough to pass.
