What does the author of the Satcharitra say about his own role and qualifications for writing the book in this chapter?

In Chapter 30, the author expresses profound humility regarding his role in composing the text. He questions his own qualifications, asking who would take up such a task. He concludes that the work is not truly his, but that Sai Baba, the one whose work it is, gets it accomplished. The author views himself as a mere vessel, stating, 'Sai is the illuminator of my speech' and 'the capable lamp of knowledge.' Because of his complete faith in the compassionate Lord, he felt no effort, and the wavering of his mind was stilled.
