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

In Chapter 30, the author humbly reflects on his own qualifications, or lack thereof, for undertaking the task of writing the Satcharitra. He poses the question, "what qualification do I have?" and concludes that he is merely a vessel, stating that the work belongs to Sai Baba, and it is Sai who gets it accomplished. The author describes Sai as the "illuminator of my speech" and a "capable lamp of knowledge" who destroys the darkness of ignorance. This faith in Sai as the true doer, as mentioned in the chapter, stilled the wavering of the author's mind and made the effort feel slight, reinforcing that the text itself is a product of Sai's grace.
