I've heard the intended conclusion of Shri Sai Satcharita is missing. Can you elaborate on what happened and what the final chapters contain instead?

That is an astute observation about the book's composition. According to information in Chapter 0, the author, Annasaheb, had planned to include a summary and conclusion in the 52nd chapter. However, these sections are not found in the published book. The prevailing belief, as mentioned in Chapter 0, is that the original slips of paper containing these verses were unfortunately lost, as it was Annasaheb's habit to write on such slips. Despite this, Annasaheb himself declared "The Shri Sai Satcharita book is now complete" in the Shri Sai Leela magazine. The published 52nd chapter, instead of a summary, contains profound content on the greatness of the Sadguru, the spiritual benefits of reading the text, and a heartfelt prayer from the author for grace. The entire work consists of 53 chapters.
