How does the author of the Sai Satcharita describe his own role and capability in writing the text?

In Chapter 30, the author expresses profound humility about his role in creating the text. He questions his own qualifications, stating, "what qualification do I have? Who takes up this task upon themselves?" He clarifies that the work is not his own but is accomplished by Sai Baba Himself. The author sees himself merely as a vessel, explaining, "Though I am (merely a vessel), Sai is the illuminator of my speech. Sai is the capable lamp of knowledge." This faith in Sai as the true doer stills the wavering of his mind and removes any apprehension about the task.
