What is the philosophical perspective on the purpose of human life presented in Chapter 8?

Chapter 8 of the Sai Satcharitra presents a profound philosophical argument about the purpose of human existence. It posits that the true duty of human birth is the attainment of the Supreme Self (Paramatman). The text critically questions a life spent merely on basic activities like eating, sleeping, and procreation, comparing it to the existence of dogs and pigs. As stated in Chapter 8, if nourishing the body and pursuing sexual pleasure are the only ends, then the human birth is considered useless. It urges the reader to use wisdom to understand that a human is meant to be free, fearless, and independent, and that the realization of the Eternal is the true measure of a successful life.
