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

In Chapter 30, the author humbly describes himself as merely a vessel or instrument for a divine task. He questions his own qualifications, stating, "what qualification do I have? Who takes up this task upon themselves?" He firmly believes that the work is not his own but that of Sai Baba, who "Himself gets it accomplished." The author explains that Sai is the "illuminator of my speech" and the "capable lamp of knowledge" who destroys ignorance. Because of his complete faith in the compassionate Lord, he feels no effort in the writing process, and the wavering of his mind is stilled.
