What does Chapter 8 of the Sai Satcharitra teach about the true purpose of human life, especially when compared to animals like dogs and pigs?

Chapter 8 of the Sai Satcharitra explains that the true duty and success of human birth is the attainment of the Supreme Self (Paramatman). It questions whether life is merely for growing strong and living long. The text argues that if life is only spent on activities like eating, sleeping, fear, and mating, then there is no difference between a human and a dog or a pig. As stated in Chapter 8, dogs also fill their bellies and reproduce, so the greatness of the human body lies in pursuing the realization of the Eternal, which makes a person truly free and fearless.
