Why does the author of Sai Satcharitra compare human life to that of dogs and pigs in Chapter 8?

In Chapter 8 of the Sai Satcharitra, the comparison of human life to that of dogs and pigs serves as a powerful rhetorical tool to underscore the importance of spiritual pursuits. The author argues that if a person's life is solely dedicated to nourishing the body and engaging in sexual pleasure, then this human birth is useless. The text pointedly asks wherein the greatness of the human body lies if its functions are the same as those of animals who also fill their bellies and reproduce. According to the philosophy presented in Chapter 8, this comparison is meant to provoke readers into realizing that the true purpose of their existence is higher than mere survival; it is the attainment of the Supreme Self, a goal that distinguishes humans from other creatures.
