What are the teachings in Chapter 11 regarding the perishable body and the eternal nature of Sai Baba?

Chapter 11 teaches that the physical body is perishable and will eventually come to an end, and therefore, a devotee should not grieve over this fact but should instead focus on the eternal. The text explains that the entire visible creation, from the creator down to a blade of grass, is born from the Unmanifest and ultimately merges back into it. This means there is no true death for anyone. Based on this principle, the chapter asks how there can be death for Baba, concluding that Shri Sai is eternally pure, enlightened, untainted, and deathless, existing beyond the limitations of the physical form.
