According to Chapter 8 of the Sai Satcharitra, what is the true purpose of human life, and how is it distinguished from the existence 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 strongly argues against a life spent merely on survival activities like eating, sleeping, and procreation. It questions the value of human existence if it is reduced to these functions, asking what dogs and pigs lack in that regard. The chapter states that if nourishing the body and sexual pleasure are the only goals, then human birth is useless. True success, as described in Chapter 8, is the realization of the Eternal, which is possible because a human being is uniquely free, fearless, and independent.
