How does the author, Hemadpant, describe his role in writing down Sai's stories?

In Chapter 47, the author, referred to as Hemad, portrays himself as a humble instrument for a divine purpose, rather than the true originator of the stories. He states that "Sai is the eye of the eyes and the ear of the ears; Entering my heart, He himself narrated this account." This suggests that Sai Baba is the actual speaker. The author goes so far as to say that "Sai Samarth himself is the story, the speaker, and the face; In that case, who is Hemad? He is merely a nickname." He emphasizes that without grasping the essence of these divinely inspired tales, he is as empty as any other listener, highlighting his role as a conduit for Sai's wisdom.
