Who is the true author of the Shri Sai Satcharitra according to the text itself?

According to the concluding thoughts in Chapter 50, while Hemadpant is the scribe, he is considered only a 'nominal cause' in the creation of the Shri Sai Satcharitra. The text explicitly states that one should 'leave aside Hemadpant,' as there is 'no one other than Sai who makes the words speak.' It further elaborates that Sai is simultaneously the subject being heard, the act of hearing, and the listener. This establishes that the book's true author and source is believed to be Sai Baba himself, with Hemadpant serving as the humble instrument for the welfare of devotees.
