Besides the story of Devidas, what else does the author of Chapter 5, Hemadpant, tell us about the Sai Satcharitra itself?

In the concluding sections of Chapter 5, the author, Hemadpant, provides a meta-narrative about the book's structure and content. After finishing the story of the Guru and disciple, which he notes was originally told by Mahalsapati, Hemadpant builds anticipation for what is to come. He states that 'the next narrative is even more profound' and gives a preview of future topics. As detailed in Chapter 5, these include the history of the mosque, the enduring mystery of whether Sai was of Hindu or Muslim lineage, and how Baba experienced his devotees' sufferings through his own actions like washing clothes, grinding, and performing Khanda-yoga. The chapter ends with Hemadpant's personal surrender to Sai, framing the act of writing as an act of grace.
