According to Baba's philosophy, what is the ultimate purpose of human existence?

The philosophy detailed in Chapter 8 posits that the true purpose of human life transcends mere survival and pleasure. While much of life is spent in sleep, restlessness, and fleeting stages like childhood play and youthful passion, the text questions if this is all there is. It asserts that the true duty and success of human birth is the attainment of the Supreme Self (Paramatman). If life is only about nourishing the body and sexual pleasure, then this human birth is considered useless, no different from the existence of dogs or pigs.
