What is the mindset of the person who ultimately takes on the task of writing the summary in Chapter 53?

The narrator who takes on the task of writing the summary in Chapter 53 expresses profound humility and self-doubt. They describe themself as a "fool with a dull intellect" with no knowledge or poetic ability. The author feels dejected and prays to Lord Dattaguru for mercy, stating, "I have no strength to compose poetry." They believe the only way the summary can be written is through the Guru's grace, whose power can "make a gnat lift a mountain." Ultimately, they see themself as merely an instrument, asserting that Sai himself will be the one to write the summary.
