In Chapter 30, what does the author of the Sai Satcharita reveal about his own role and qualifications for writing the book?

In Chapter 30, the author expresses profound humility regarding his role in writing the Sri Sai Satcharita. He openly questions his own suitability, asking, "what qualification do I have? Who takes up this task upon themselves?" He firmly believes that he is merely an instrument and that Sai Baba is the true doer. The author describes Sai as the "illuminator of my speech" and the "capable lamp of knowledge" who is responsible for the work's creation. This chapter conveys the author's conviction that the entire project is accomplished by Sai Himself, stating, "He whose work it is, He Himself gets it accomplished. What burden is there on me then?"
