I heard the final chapters of the Shri Sai Satcharita have a complicated history. Can you explain what happened?

Yes, there is a notable history regarding the book's conclusion. The author, Annasaheb, originally intended for the 52nd chapter to include a summary (Simhavalokan) and a conclusion (Avataranika). However, as the preface in Chapter 0 explains, Annasaheb had a habit of writing on slips of paper. The slips containing these specific concluding verses were apparently lost or forgotten before publication. Consequently, the published 52nd chapter focuses only on the Sadguru's greatness and the benefits of reading the text. To provide a proper ending, a new, separate 53rd chapter was later prepared and added, completing the overall structure of the book we have today, as detailed in chunks 16 and 17.
