Naguib Mahfouz's "Palace Walk" explores the themes of morality and the benefits of performing good deeds. The quote, "In the calculus of good deeds you have the most to gain," suggests that engaging in positive actions not only benefits others but also brings the performer a greater sense of fulfillment and reward. It emphasizes the idea that good deeds create a ripple effect that enhances one's own life and the community as a whole.

This perspective aligns with Mahfouz's broader narrative, where the characters navigate their personal beliefs and societal obligations. Through their choices, readers witness how positive actions can lead to growth and strengthen relationships. Ultimately, the quote encapsulates the notion that embracing goodness is a pathway to personal and communal elevation.
