What does Chapter 43 reveal about Sai Baba's true nature in relation to the physical world and the concepts of birth and death?

Chapter 43 explains that Sai Baba's true nature is that of the 'complete Supreme Brahman' and a 'mass of bliss.' From this perspective, the world is an illusion, and he is devoid of bodily consciousness. For a being who doesn't perceive the birth of a body, the concept of its death is meaningless. The chapter describes birth and death as 'false imaginations' for avatars like him, who incarnate solely for the welfare of their devotees. His departure was a conscious choice to merge back into his 'previous unmanifest state,' demonstrating that he transcends the material realm and is not bound by its laws.
