How does the Satcharita describe the nature of birth and death, particularly in relation to Sai Baba?

Chapter 43 explains that birth is the union of the body and senses, while death is their separation. However, for a divine being like Sai Baba, these concepts are considered 'false imaginations.' The text posits that Sai Samarth is the complete Supreme Brahman, for whom birth and death are irrelevant because he is devoid of bodily impulses. His physical manifestation and departure are described as a voluntary act undertaken for the welfare of his devotees. The chapter emphasizes that death is a characteristic of the physical body, but Baba, having transcended this, burned his body in the 'fire of Yoga' to merge back into his unmanifest form.
