From the perspective of Chapter 8, why is a life spent without seeking spiritual realization considered a waste?

Chapter 8 of the Sai Satcharitra argues forcefully that a life devoid of spiritual seeking is a wasted opportunity. It posits that half of life is lost to sleep and the rest to restlessness, with childhood spent in play, youth in passion, and old age in infirmity. The chapter asks rhetorically if the purpose of human existence is merely to survive, comparing such a life to that of dogs and pigs, who also eat, sleep, and reproduce. As explained in this chapter, the human body is transient, like the ever-changing flame of a lamp, and ultimately an impure vessel. Therefore, to use this precious human birth only for nourishing the body and for sensual pleasure is considered useless, as the true success of being human lies in realizing the Eternal.
