Besides the main story, what other topics or future events are foreshadowed at the conclusion of Chapter 5?

At the end of Chapter 5, after concluding the story of Devidas and the Fakir, the author Hemadpant provides a preview of subsequent narratives. The chapter mentions that the story of the Guru and disciple was originally told by Mahalsapati. It then teases future topics, creating anticipation for what's to come. These include an account of the mosque's previous condition and the difficulty in paving its floor, the unresolved question of whether Sai was of Hindu or Muslim lineage, and a description of Baba's yogic practices like washing clothes, grinding, and Khanda-yoga, through which he experienced the sufferings of his devotees.
