Why does Chapter 8 of the Sai Satcharitra compare a human focused only on survival to animals like dogs and pigs?

Chapter 8 of the Sai Satcharitra employs a stark comparison between humans and animals to emphasize the unique potential of human birth. The text argues that if a person's life is devoted only to eating, sleeping, and reproduction, their existence is functionally the same as that of dogs or pigs, who also perform these actions to survive. As the chapter questions, if this is the only purpose, "what do dogs and pigs lack?" This rhetoric is used to provoke the reader into contemplating a higher purpose beyond mere physical survival. The ultimate point made in Chapter 8 is that the true duty of a human is the spiritual goal of attaining the Supreme Self, which distinguishes human life from animal life.
