How does the author who completes the Shri Sai Satcharitra describe his own capabilities in Chapter 53, and what does he believe is the true source of his ability to write?

In Chapter 53, the author who takes over the task of writing the summary expresses profound humility and self-doubt. He describes himself as "a fool with a dull intellect, having no scent of knowledge" and feels dejected about the task. He states, "I have no strength to compose poetry. The Guru knows my dullness." Despite his feelings of inadequacy, he finds support in the grace of the Guru. As detailed in Chapter 53, he firmly believes that his ability to write comes not from himself but from a higher power, praying to Lord Dattaguru and Sai-Narayana. He concludes that Sai himself will be the one to write the summary and that his own mouth is "merely an instrument."
