Who does the author credit with writing the Sai Satcharitra in Chapter 49, and what was his own role in the process?

In Chapter 49, the author, Hemadpant, humbly states that he is merely an instrument and that Sadguru Sainath is the true author of the Satcharita. He describes how Sai directly inspired the work, stating, 'He Himself is the composer and the writer.' The author reveals that whenever he felt lazy or forgot the narrative, Sai would provide the remembrance at the right time. He couldn't even choose to rest, as a story would manifest so unexpectedly that he was compelled to pick up his pen. Therefore, he concludes that the merciful Sainath entered his mind and got His own book written, fulfilling the author's desires in the process.
