According to the philosophy presented in Chapter 8, what is the true purpose of human life, and how is it distinguished from the existence of animals?

Chapter 8 of the Sai Satcharitra posits that the true duty and success of human birth is the attainment of the Supreme Self, or Paramatman. The text argues that if life is spent merely on activities like eating, sleeping, mating, and avoiding fear, then there is no significant difference between a human and animals like dogs or pigs, which also fulfill these basic survival needs. The author states that a human is meant to be free, fearless, and independent, and that realizing the Eternal is the ultimate success of birth, making a life focused only on bodily nourishment and pleasure ultimately useless.
