According to the philosophy presented in Chapter 8, what is the true purpose of human life, and how does it distinguish humans from other living beings?

Chapter 8 of the Sai Satcharitra presents a profound philosophy on the purpose of human existence. The text argues that the true duty of a human birth is the attainment of the Supreme Self (Paramatman). It strongly contrasts this with a life spent merely on survival activities like eating, sleeping, and procreation, which it notes that animals like dogs and pigs also do. The chapter poses a rhetorical question: if life is only about nourishing the body and sexual pleasure, then human birth is useless. Therefore, according to the teachings in this chapter, the unique greatness of human life lies in the capacity for self-realization and knowing the Eternal, which transcends the basic instincts shared with animals.
