According to Chapter 8, what is the true purpose of human life, and how is it contrasted with a wasted existence?

Chapter 8 of the Sai Satcharitra presents a profound philosophical discourse on the purpose of human life. It states unequivocally that the true duty and success of human birth lie in the attainment of the Supreme Self (Paramatman). The text contrasts this noble goal with a wasted existence, which it defines as a life spent merely on the four activities of eating, sleeping, fear, and mating. As this chapter argues, if life is reduced to nourishing the body and seeking sensual pleasure, it is no different from the life of an animal, such as a dog or a pig. This comparison emphasizes that the unique potential of human birth is squandered without the pursuit of spiritual realization.
