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

Chapter 8 of the Sai Satcharitra presents a profound philosophical view on human existence, stating that the true duty of human birth is the attainment of the Supreme Self (Paramatman). The text argues against a life spent merely on survival activities like eating, sleeping, and reproducing, which it equates to the existence of dogs and pigs. As described in Chapter 8, if life is wasted only on these basic functions, the human birth is considered useless. The chapter emphasizes that a human being is meant to be free, fearless, and independent, and that the true success of birth is the realization of the Eternal, not just physical sustenance.
