Based on Chapter 52, who was chosen to write the Sai Satcharitra and what was the book's main purpose?

Chapter 52 explains that Hemadpant was chosen by Sai Baba to write the book, referred to as "Sai Leela." It is specifically mentioned that Hemadpant was "devoid of specialized knowledge and learning," but Sai held his hand and caused the true life story to be written. The primary purpose of the book was to remember the experiences Sai gave to His devotees while He was in his body. As stated in Chapter 52, this life story provides enlightenment for this world and the next, and Sai kept his fame recorded in writing for the salvation of his devotees.
