According to Chapter 8 of the Sai Satcharitra, what is the true purpose of human life, and how does it contrast with a life of mere survival?

Chapter 8 of the Sai Satcharitra posits that the true duty and success of human birth is the attainment of the Supreme Self (Paramatman). The text strongly critiques a life spent only on basic activities such as eating, sleeping, and procreation, arguing that such an existence is useless. It draws a stark comparison, asking what dogs and pigs lack if survival is the only goal, as they also fill their bellies and reproduce. The chapter asserts that if a human life is wasted on these four activities—eating, sleeping, fear, and mating—then there is no meaningful difference between a human and an animal, emphasizing that the human form is meant for the higher purpose of realizing the Eternal.
