What is the philosophical perspective on death and eternity presented in Chapter 11, particularly in relation to Sai Baba?

Chapter 11 presents a profound philosophical view on death, teaching that the physical body is perishable and will end, so devotees should not grieve but focus on the eternal. It explains that the entire visible creation, from the creator down to a blade of grass, emerges from the womb of the Unmanifest and ultimately merges back into it. Based on this principle, the chapter argues that there is no real death for anyone. Consequently, it poses the question of how there can be death for Baba, concluding that Shri Sai is eternally pure, enlightened, untainted, and deathless, as his true nature is that of the beginningless and endless Unmanifest.
