How did the author who ultimately finished Chapter 53 perceive their own ability to write the summary?

The author who took on the task of completing the Shri Sai Satcharitra expresses profound humility and a feeling of inadequacy in Chapter 53. Upon realizing the summary was still missing, the author felt dejected and described themself as a "fool with a dull intellect, having no scent of knowledge" and being "blind to poetry from the start." Instead of feeling confident, the author turned to prayer, begging Lord Dattaguru for mercy and grace to complete the work. They believed they had no personal strength for the task but found solace and support in the Guru's power, which is described as great enough to "make a gnat lift a mountain," showcasing a complete surrender to divine will.
