Based on Chapter 53, what was Sai Baba's role in the completion of the Shri Sai Satcharitra?

Chapter 53 emphasizes that Sai Baba's will is the ultimate force behind the creation and completion of the Satcharitra. The chapter notes that Hemadpant's inability to finish the book was an exception to the rule, suggesting "Baba’s will is more powerful." The new author, feeling incapable of the task, surrenders completely to the Guru. He asserts that Sai Baba, referred to as "the breaker of obstacles (Vakratunda)," would be the true author of the summary. As stated in Chapter 53, the author sees himself as merely an instrument, declaring, "His glory is immense; my mouth is merely an instrument." This illustrates the core belief that the Guru inspires and works through the devotee.
