What is the book's philosophical take on death, especially concerning someone like Sai Baba?

Chapter 43 provides a deep philosophical perspective on death, contrasting it for ordinary beings and enlightened souls like Sai Baba. It defines birth as the union of body and senses and death as their separation. For most, death is an inseparable part of life. However, for great beings who incarnate by their own will, birth and death are considered 'false imaginations.' The text describes Sai Baba as the 'complete Supreme Brahman' and a 'mass of bliss' for whom physical birth and death are irrelevant. It posits that he had already 'killed death' and could not be touched by it, as he was devoid of bodily impulses and consciousness of the body. His departure was a willed act of merging into the unmanifest.
