Based on Chapter 8, what is the difference between a wasted life and a successful one?

According to the teachings in Chapter 8 of the Sai Satcharitra, a life is considered "useless" if it is spent solely on nourishing the body and pursuing sensual pleasures, activities common to all creatures. The text explicitly asks what the difference is between a human and a dog if life is only about eating, sleeping, fear, and mating. In contrast, a successful human life is defined by realizing its true purpose. Chapter 8 states that a human being is meant to be free, fearless, and independent, and that the "true success of birth" is the realization of the Eternal. It urges self-inquiry, posing fundamental questions like "Where have we come from? Who are we?" to guide a person toward this higher purpose.
