What does Chapter 8 of the Sai Satcharitra teach about the true purpose of human life, as opposed to simply existing?

Chapter 8 presents a profound philosophy on human life, arguing that its true purpose is the attainment of the Supreme Self (Paramatman). The text questions whether life is merely for being born, growing, and breathing. It states that if life is only about activities like eating, sleeping, fear, and mating, then there is little difference between a human and a dog or a pig. As detailed in Chapter 8, the real success of human birth is the realization of the Eternal, and a person who understands the "seed" of their existence—where they came from and who they are—is truly proficient.
