At the heart of the narrative is Keller's relationship with her teacher, Anne Sullivan, who played a critical role in helping her break through the isolation of her disabilities by teaching her language and giving her the tools to express herself. The famous breakthrough moment where Sullivan spelled "water" into Helen's hand is a pivotal moment in the book and in Keller's life.Keller goes on to describe her education, her love of learning, and her experiences at Radcliffe College, where she became the first deaf-blind person to earn a Bachelor of Arts degree. The autobiography not only recounts her personal growth but also offers reflections on her philosophy of life, perseverance, and the importance of education.
