What does Chapter 30 say about the author's personal feelings and his role in writing the Sai Satcharita?

In Chapter 30, the author, Hemadpant, expresses profound humility regarding his role in composing the Sri Sai Satcharita. He questions his own qualifications, stating, 'what qualification do I have?' and sees himself merely as a vessel. He firmly believes that Sai Baba is the true doer, the one who is getting the work accomplished through him. The chapter beautifully articulates this by calling Sai the 'illuminator of my speech' and a 'capable lamp of knowledge' that destroys the darkness of ignorance. This faith in Sai's compassionate guidance is what stilled the author's wavering mind and made the monumental task feel effortless.
