How does the author of Chapter 53 articulate their feelings of inadequacy and reliance on divine grace to complete the summary?

The author of Chapter 53 expresses profound humility and a sense of being unqualified for the task. As detailed in the chapter, upon realizing the summary was missing, the author's mind became dejected. They describe themselves as a 'fool with a dull intellect, having no scent of knowledge' and 'blind to poetry from the start.' Consequently, the author turns to prayer, begging for mercy from Lord Dattaguru. They express a complete reliance on divine power, believing the Guru 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 a mere instrument.
