According to Chapter 14 of the Sai Satcharitra, what is the purpose of human life and what makes it distinct from animal existence?

Chapter 14 of the Sai Satcharitra teaches that human birth is exceptionally fortunate because it alone provides the opportunity to achieve devotion to God, attain the four types of liberation, and realize the Self. The text distinguishes this from animal existence by stating that a person who knows nothing beyond food, sleep, fear, and procreation is merely like an animal "without a tail and horns." As detailed in chapter 14, if one does not use this life to pursue spiritual understanding, their birth is considered a "useless burden on the earth." The true greatness of human birth lies in using it for these higher spiritual pursuits, which makes life meaningful.
