In Jodi Picoult's novel "Change of Heart," a profound insight is shared about the limitations of language in expressing deep emotions. The idea is that while words are our primary tools for communication, they often fail to encapsulate the full spectrum of human experience, such as joy, grief, or love. The metaphor of words as nets suggests they can catch some meaning but will always leave a great deal unrepresented.

This reflects the inherent struggle of trying to articulate feelings that are profoundly personal. Events like falling in love or having a spiritual experience can be life-changing, yet sharing the essence of those moments can be challenging. The author emphasizes that although we strive to communicate our inner worlds, the richness of these experiences often eludes verbal capture, reminding us of the limits of language.
