How does the author of the Sai Satcharitra describe his own role and qualifications for writing the text in Chapter 30?

In Chapter 30, the author expresses deep humility about his role in composing the Sri Sai Satcharita. He questions his own qualifications, asking, "what qualification do I have?" and suggests he is merely a vessel. The author firmly believes that Sai Baba is the true force behind the work, stating, "He whose work it is, He Himself gets it accomplished." He views Sai as the "illuminator of my speech" and a "capable lamp of knowledge," which stills the wavering of his mind and removes any apprehension, making him feel that no effort was required on his part.
