According to Chapter 8, what distinguishes a meaningful human life from mere animalistic existence?

In a profound philosophical section, Chapter 8 of the Sai Satcharitra argues that the true purpose of human life is the attainment of the Supreme Self (Paramatman). The text differentiates a meaningful life from mere existence by questioning what separates humans from animals like dogs and pigs if life is reduced to the four activities of eating, sleeping, fear, and mating. As stated in this chapter, if nourishing the body and seeking sensual pleasure are the only goals, then the precious human birth is considered useless. The true greatness and duty of being human lies in using this life to realize the Eternal, a potential not available to other creatures.
