What is the overall structure of the Shri Sai Satcharita, and what happened to its final chapter?

According to the preface in Chapter 0, the Shri Sai Satcharita is primarily structured with 51 chapters, each containing sections on Vedanta, the Guru's glory, and a related story. The original plan was for a 52nd chapter to provide a summary and conclusion. However, the slips of paper containing these verses were evidently lost. The published Chapter 52, therefore, contains different content, focusing on the greatness of the Sadguru and the fruits of reading the book. To resolve this, as explained in the preface, a new concluding chapter was prepared and added to the book as the 53rd chapter, completing the overall structure of this sacred text.
