What does the author of the Sai Satcharitra reveal about his experience of writing the book in Chapter 30?

In Chapter 30, the author reflects on his role in creating the Sri Sai Satcharita with great humility. He questions his own qualifications, asking, 'what qualification do I have?' He firmly believes that he is merely an instrument and that Sai Baba is the true doer, stating, 'He whose work it is, He Himself gets it accomplished. What burden is there on me then?' As described in Chapter 30, the author sees Sai as the 'illuminator of my speech' and a 'capable lamp of knowledge,' whose grace stilled his wavering mind and made the task feel effortless.
