Why did Hemadpant emphasize that he is not the true author of the Satcharitra?

In Chapter 50, the text clarifies the role of Hemadpant to guide the reader's perspective. It states that Hemadpant is merely a 'nominal cause,' an instrument used for the true welfare of the devotees. The reader is explicitly told to 'leave aside Hemadpant' because he is not the doer of this Satcharitra. The true speaker, the one who makes the words speak, is none other than Sai Baba himself. This instruction is given to foster a sense of non-duality, encouraging the reader to see Sai as the subject, the act of reading, and the reader, all in one unified state, thereby purifying the heart through devotion.
