How does Hemadpant conclude Chapter 5, and what topics does he foreshadow for upcoming chapters?

Chapter 5 concludes with the author, Hemadpant, surrendering to Sai and affirming the purifying power of these stories. He notes that the tale of Devidas was originally narrated by the great devotee Mahalsapati. After this, Hemadpant provides a preview of subsequent narratives, stating that what follows is "even more profound." As mentioned at the end of Chapter 5, he promises to narrate stories about the original condition of the mosque in Shirdi, the mystery of Sai's lineage (whether Hindu or Muslim), and how Baba performed acts like washing clothes, grinding grains, and practicing Khanda-yoga, through which he took on the sufferings of his devotees.
