Based on Chapter 43, what specific events leading up to Sai Baba's Mahasamadhi does the author intend to narrate?

Chapter 43 acts as a guide, outlining the specific events surrounding Sai Baba's Mahasamadhi that the author will narrate. It explicitly mentions several key occurrences. First, it details how, as his death drew near, Sai arranged to listen to the Ramayana for his benefit, read by a Brahmin. Second, the chapter promises to explain how the planning for his Samadhi (tomb) took place. This includes the story of the unseen 'fall of the brick' which was a precursor to the Samadhi's planning. Lastly, as Chapter 43 points out, the author will also recount a past incident where Baba seemed dead for three days but then returned to his body, demonstrating his power over life.
