According to the teachings in the Satcharitra, what distinguishes the purpose of human life from that of animals like dogs or pigs?

The Shri Sai Satcharitra explains that if a human life is spent only on activities like eating, sleeping, fear, and mating, there is little difference between a human and a dog. As detailed in Chapter 8, the true duty and purpose of human birth is the attainment of the Supreme Self, or Paramatman. The text poses the question: if nourishing the body and sexual pleasure are the only goals, then this human birth is useless. Animals like dogs and pigs also fill their bellies and reproduce, so the greatness of the human body lies in using it to pursue this higher spiritual purpose rather than mere survival.
