The "Book of Life" is a concept found in various religious traditions, often symbolizing a record of individuals' deeds and their ultimate fate in the afterlife. In Christianity, it is believed to contain the names of those who will attain eternal life, while in Judaism, it is associated with the Yom Kippur observance, where names are inscribed or erased based on one's actions. In Islam, a similar idea exists, where the deeds of individuals are recorded by angels, influencing their judgment on the Day of Resurrection. The "Book of Life" serves as a metaphor for moral accountability and the consequences of one's actions throughout their life.
