How does the author of Chapter 53 express his feelings about taking on the difficult task of writing the book's summary?

The author who undertook writing the summary in Chapter 53 expresses profound humility and a sense of inadequacy for the task. He describes himself as a 'fool with a dull intellect' who is 'blind to poetry from the start.' Feeling dejected, he turns to prayer, begging for mercy from Lord Dattaguru. He acknowledges that he has no strength to compose poetry on his own and relies entirely on the Guru's grace. As mentioned in Chapter 53, he believes the Guru's power is so great that it 'can make a gnat lift a mountain' and that ultimately, Sai himself will be the one to write the summary, using the author's mouth as an instrument.
