What do Sai's teachings in Chapter 19 reveal about the ultimate purpose of human life and how to achieve it?

The teachings in Chapter 19 reveal that the fulfillment of the soul and the primary duty of human birth is the attainment of the Supreme Self. This ultimate goal is characterized by achieving a state of eternity, fearlessness, liberation, and independence. To achieve this, one must realize the true nature of the Soul as pure, changeless consciousness, which is distinct from the body and mind. The text clarifies that this realization is impossible without knowledge, and knowledge requires detachment from the world, which is perceived as transient and illusory like a dream. While knowledge is the key, Baba also advised the path of devotion (Bhakti) as an easier, sweeter means for common people to break the bonds of worldly existence and progress toward this ultimate purpose.
