What does Chapter 8 of the Sai Satcharitra teach about the true purpose of human existence, and how does it distinguish this from the life of animals?

Chapter 8 of the Sai Satcharitra posits that the true duty and purpose of human birth is the attainment of the Supreme Self (Paramatman). The text argues that if life is spent only on activities like eating, sleeping, procreation, and fearing, there is no significant difference between a human and animals like dogs or pigs. As described in the chapter, dogs also fill their bellies and reproduce, so if a human's life is limited to nourishing the body and sexual pleasure, that birth is considered useless. The chapter emphasizes that a human is meant to be free and independent, and the true success of birth is the realization of the Eternal.
