According to Chapter 5, who is responsible for narrating the story of the Guru and disciple, and what future events does the chapter foreshadow?

In Chapter 5 of the Sai Satcharitra, it is explicitly mentioned that the story concerning the Guru (the Fakir) and the disciple (Sai Baba) was made known by Mahalsapati, who is described as a great devotee of Sainath. The author, Hemadpant, assures the reader that the account has been told exactly as it happened. The chapter then acts as a bridge to future narratives, promising that the next stories are even more profound. It foreshadows topics that will be discussed later, such as the original condition of the mosque, the paving of its floor, the mystery of Sai's lineage, and Baba's practices of washing clothes, grinding, and performing Khanda-yoga.
