What role did Sai Baba Himself play in the writing of the Satcharita, according to the author in Chapter 49?

In Chapter 49, the author asserts that Sai Baba was the direct and active force behind the creation of the Satcharita. He states that Sai is both the "composer and the writer" and that without His inspiration, the work would be dry. The author claims that the "merciful Sainath, entering into my mind, got His own book written." He provides examples of this divine intervention, explaining that if he ever forgets the narrative, Sai gives him remembrance at the right time, and that stories manifest so unexpectedly that he is compelled to pick up his pen and write.
