How does the author of the Sai Satcharitra describe their own role in writing the book in Chapter 30?

In Chapter 30, the author humbly expresses their own perceived lack of qualification for the task of writing the text. They pose the question, "what qualification do I have?" and conclude that the burden is not on them because Sai Baba Himself is the one getting the work accomplished. The author sees themselves merely as a vessel, stating, "Sai is the illuminator of my speech" and "the capable lamp of knowledge." This faith in Sai as the true author stills the wavering of their mind and removes any apprehension about the monumental task.
