The quote from Peter S. Beagle's "Once Upon a Curse: Stories and Fairy Tales for Adult Readers" encapsulates the theme of belief and choice. In a moment shrouded in darkness, a deep connection is formed through trust, suggesting that faith can sometimes be an act of will rather than a reflection of certainty. This highlights the complex nature of belief, suggesting it often stems from personal choice rather than objective truth.

This exploration of belief resonates throughout the stories in the book, emphasizing the struggles characters face in distinguishing between reality and illusion. By choosing to believe, they embark on journeys that test their understanding of love, loyalty, and the mythical elements of their lives. Beagle's work invites readers to reflect on their own beliefs and the choices that shape their perceptions of the world, making it a profound reflection on human experience.
