How does Chapter 43 explain the nature of enlightened saints like Sai Baba in relation to the concepts of birth and death?

Chapter 43 presents a deep philosophical view, explaining that for enlightened beings, birth and death are illusions tied to the physical body, which they see as a mere adjunct. The text posits that 'the union of body and senses is birth; the separation of body and senses is death.' Saints like Baba, who are described as a 'mass of bliss' and the 'complete Supreme Brahman,' are beyond these bodily impulses. They incarnate by their own will, with the sole desire for the welfare of devotees, and are not touched by birth or death. For them, death is like 'dust,' a false imagination, as they have already transcended the body even while living in it.
