Describe the sequence of events that led to the need for a new author to complete the Shri Sai Satcharitra, as detailed in Chapter 53.

Chapter 53 recounts the events following the original author Hemadpant's promise to provide a final summary. Firstly, it's noted that the summary was not extracted, possibly due to forgetfulness or, as the text suggests, because "Baba’s will is more powerful." The critical event was Hemadpant's sudden death, which left the book incomplete. His son, Gajanan, then reviewed his father's vast records. After the missing summary was confirmed, others, including Babasaheb Tarkhad, agreed it must be written. A deadline was even announced in the Shri Sai Leela magazine, but it passed without the summary appearing, leading the new author to pray for divine assistance to complete the sacred task.
