What is the philosophical perspective on birth and death presented in the text, and how does it apply to saints like Sai Baba?

Chapter 43 presents a distinct philosophy where birth is the union of body and senses, and death is their separation—an inseparable pair. However, it clarifies that this framework applies to ordinary beings. For great souls and avatars who incarnate by their own will for the welfare of devotees, birth and death are considered "false imaginations." As Chapter 43 states, Sai Baba is the "complete Supreme Brahman" for whom the world is an illusion and consciousness of the body is absent. Therefore, the concepts of birth and death are irrelevant to his true nature. His life is not a modification of the body but a manifestation of will, and his departure is not an end but a merging into his unmanifest state.
