Who finished the final chapter and summary of the Sai Satcharitra, and what was their mindset while doing so?

Chapter 53 reveals that after Hemadpant's death, another devotee undertook the task of writing the concluding summary. This person expresses profound humility, describing himself as a "fool with a dull intellect" who has "no scent of knowledge" and is "blind to poetry from the start." He felt dejected that the summary was missing and prayed earnestly to Lord Dattaguru and Sai-Narayana for mercy and inspiration. He believed he had no personal strength to compose the work but that with the Guru's grace, even a "gnat could lift a mountain." Ultimately, as stated in Chapter 53, he viewed himself merely as an instrument, asserting that Sai Baba himself, the "breaker of obstacles," would be the true author writing through him.
