In the book, Tolle asserts that everyone can find "the freedom and joy of life" if they live in the present moment. According to Tolle, the book's purpose "is not to add new information or beliefs to your mind or to try to convince you of anything, but to bring about a shift in consciousness". Tolle's intent is to change the way human beings think, and he envisions a world population that is increasingly humble, enlightened, and pure.

An article in Success magazine describes A New Earth as a "self-improvement book" that encourages its readers to live their lives in each present moment and to create happiness for themselves without emphasizing material possessions.
