How does Chapter 52 characterize the author Hemadpant's role and the origin of the Satcharitra?

Chapter 52 presents Hemadpant's role as one chosen by divine will rather than by scholarly merit. The text explicitly states that Sai Baba selected Hemadpant, who was 'devoid of specialized knowledge and learning,' and by holding his hand, 'caused this true life story to be written.' This implies that the book is a product of Sai's grace and inspiration, channeled through Hemadpant. The chapter further clarifies that the inspiration for the book came after Sai departed to His own abode, drawing upon the fame and stories He had narrated with His own mouth for His disciples to hear.
