What specific challenges arose in compiling the final summary of the Shri Sai Satcharitra after Hemadpant's passing, as detailed in Chapter 53?

Chapter 53 outlines several significant challenges in completing the book. The first and most critical challenge was the sudden death of the original author, Hemadpant. Following this, his son Gajanan had to undertake 'great effort in researching' Hemadpant's vast records. Another problem was that the promised summary could not be found within the scraps of paper Hemadpant used for writing. The text also notes that after others, including Babasaheb Tarkhad, agreed the summary must be written, a deadline was set and announced in a magazine. However, 'The deadline passed, but the summary did not appear,' highlighting the difficulty in finding a suitable person and method to complete the sacred task.
