Besides the story of Devidas and the Fakir, what other topics or future events are hinted at in the conclusion of Chapter 5?

The conclusion of Chapter 5 provides a glimpse into future narratives. After telling the story of the Guru-disciple dynamic, Hemadpant mentions that the next narrative will be even more profound. Specifically, Chapter 5 foreshadows several topics that will be discussed later. These include the original state of the mosque, the difficulties encountered in paving its floor, and the unresolved mystery of whether Sai was of Hindu or Muslim lineage. The text also promises to narrate how Baba experienced the sufferings of his devotees through acts like washing clothes, grinding, and performing Khanda-yoga.
