Jay Parini's book, "Why Poetry Matters," highlights the essential role of poetry in expressing and understanding human experience. He suggests that poetry serves as a unique language that captures the nuances of emotions and thoughts, allowing individuals to articulate feelings in ways that other forms of communication might not convey effectively.

The quote, "Poetry is a language adequate to one's experience," illustrates that poetry reflects personal journeys and shared human conditions. It emphasizes the ability of poetry to resonate deeply with readers, making it a vital art form for connecting with oneself and others through the power of language and imagination.
