Can you explain the specific role Sai Baba played in the actual writing of the Satcharita, as described by the author in the 49th chapter?

In Chapter 49, the author, Hemadpant, makes it very clear that Sai Baba was the direct and active force behind the creation of the Sai Satcharitra. He states that "the merciful Sainath, entering into my mind, got His own book written." The author describes a process where Sai's inspiration was constant and indispensable. For instance, he writes, "If I forget the narrative, He gives me the remembrance at the right time," and "A story manifests so unexpectedly that I must take the pen in my hand." This reveals that Sai not only prompted the start of the book but also guided its content moment by moment, leading the author to conclude that Sai is "Himself the composer and the writer."
