According to Chapter 52, how was the author Hemadpant chosen, and what does this reveal about Sai's methods?

Chapter 52 reveals that Sai Baba chose Hemadpant to author His life story despite Hemadpant feeling he was devoid of specialized knowledge and learning. The text states that Sai held his hand and caused this true life story to be written, showing that the Guru's grace, not worldly qualification, was the deciding factor. This chapter also mentions that some of the fame and stories were narrated by Sai with His own mouth for disciples to hear, and the inspiration for the book came after He departed His body. This demonstrates Sai's method of working through his devotees, using them as instruments for a divine purpose.
