According to the preface, how is the creation of Shri Sai Satcharita an example of Guru's grace?

The preface explains that the creation of Shri Sai Satcharita is a direct result of Guru's grace. Chapter 0 highlights that the author, Annasaheb, initially had no devotion to a Guru and was proud of his own abilities. However, after his eyes met Baba's, his pride was shattered, and he became convinced of the necessity of a Sadguru. The text explicitly states that Baba's grace then fell upon him, and "the writing of Shri Sai Satcharita is the fruit of that grace." This demonstrates that without this divine intervention, the book, which is described as a grace-filled (Prasad-janya) work, would not have been possible, regardless of the author's scholarship.
