How should a devotee understand the concepts of birth and death based on this chapter?

Chapter 43 presents a philosophical understanding of existence, defining birth as the 'union of body and senses' and death as their 'separation.' For ordinary beings, these are inseparable realities. However, for great souls and avatars like Sai Baba, these concepts are viewed as 'false imaginations.' The text explains that such beings incarnate by their own will, with the sole purpose of ensuring the welfare of their devotees, and are therefore not truly 'touched' by birth and death. It posits that saints are 'essentially beyond the womb' and that when their task is complete, they do not die but rather 'merge into the unmanifest.' For Sai Samarth, who is described as the Supreme Brahman, the very notions of birth and death are irrelevant.
