What does Sai Baba teach about the ultimate purpose of human existence?

According to the teachings found in Chapter 14, the purpose of human life is twofold: to live happily in the world while also remaining constantly alert in order to make one's life meaningful. The text explains that attaining a human body is an incredibly rare opportunity, granted through the strength of 'infinite merit.' Therefore, this precious life should be used wisely. The chapter further notes that those who use this opportunity to understand spirituality are considered 'exceptionally fortunate,' suggesting that a key part of our purpose is spiritual awakening.
