What is the teaching in Chapter 11 regarding the nature of death and Sai Baba's eternal state?

Chapter 11 teaches that the physical body is perishable and will eventually end, but a devotee should not grieve this fact. Instead, one should focus on the 'beginningless and endless (Eternal).' The chapter explains that the entire visible creation emerges from the Unmanifest and merges back into it. Based on this principle, the text concludes that there is no true death for anyone. As Chapter 11 states, if this is true for all, how could there be death for Baba? It emphatically declares that Shri Sai is eternally pure, enlightened, untainted, and deathless, transcending the limitations of the physical body.
