Who was tasked with completing Chapter 53, and what challenges did they face?

The original author of the Shri Sai Satcharitra, Hemadpant, passed away before he could write the concluding summary as promised. As Chapter 53 explains, after his death, his son Gajananrao and others, including Babasaheb Tarkhad, agreed that the summary must be written. The new author, whose name is not explicitly stated in these chunks, felt immense pressure and self-doubt. He considered Hemadpant a "jewel among poets" and felt he was a "fool with a dull intellect" by comparison. This feeling of inadequacy was his primary challenge, which he overcame by praying to Dattaguru and Sai for grace, believing that Sai himself would write the summary through him.
