According to the text, what is Sai Baba's true form, and why is he considered beyond death?

Chapter 43 describes Sai Samarth as a "mass of bliss" and the "complete Supreme Brahman" for whom the concepts of birth and death are irrelevant. It posits that because the world is an illusion from the perspective of Brahman, there can be no real consciousness of the body for him. His apparent death is likened to an eclipse, which is described as merely a defect of vision, not a reality for the sun itself. The text emphasizes that Baba appeared in Shirdi due to the merits of his devotees and, having completed his task, simply merged back into his "previous unmanifest state," forever enjoying his true self.
