Why does Chapter 8 draw a comparison between humans and animals like dogs and pigs?

In Chapter 8, the comparison between human beings and animals like dogs and pigs is used as a powerful rhetorical device to question the reader's life purpose. The text posits that if a person's life revolves solely around basic survival and sensual activities—eating to fill the belly, sleeping, procreation, and fear—then there is no essential difference between that human and an animal. As this chapter of the Sai Satcharitra points out, dogs also fill their bellies and reproduce. The purpose of this stark comparison is to urge individuals to reflect with wisdom and recognize that the 'greatness of the human body' is realized only when it is used to pursue a higher goal, which is identified as the realization of the Eternal Self, rather than just existing.
