According to the Sai Satcharitra, what is the true purpose of human life, and how is it contrasted with the existence of animals?

Chapter 8 of the Sai Satcharitra presents a profound philosophical view on human existence. It argues that the true duty and purpose of human birth is the attainment of the Supreme Self, or Paramatman. The text explicitly questions whether life is merely for being born, breathing, and living long. It draws a sharp contrast with animals like dogs and pigs, stating that if human life is only spent on the four activities of eating, sleeping, fear, and mating, then this precious human birth is useless and there is no difference between a human and a dog. As Chapter 8 explains, dogs also fill their bellies and reproduce, so human greatness must lie in pursuing a higher goal.
