How did the author of the Sai Satcharitra view his own role in writing the book, based on the text in Chapter 30?

In Chapter 30, the author expresses deep humility regarding his role in composing the Sai Satcharitra. He questions his own qualifications, wondering who he is to take on such a task. He resolves this by concluding that he is merely an instrument and that the work truly belongs to Sai Baba. The author states, "He whose work it is, He Himself gets it accomplished. What burden is there on me then?" He identifies Sai as the "illuminator of my speech" and the "capable lamp of knowledge" who destroys the darkness of ignorance. This faith in Sai as the true doer stilled the author's wavering mind and removed any apprehension, allowing him to proceed with the writing without feeling the effort.
