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

In Chapter 47, the narrator, Hemad, presents his role as being merely a conduit for Sai Baba's own words. He explicitly states that Sai is the true source, describing him as "the story, the speaker, and the face." Hemad diminishes his own importance by stating, "In that case, who is Hemad? He is merely a nickname." This humility is further emphasized when he explains that Sai entered his heart and narrated the account himself. Therefore, while Hemad is the writer, he attributes the authorship and power of the stories entirely to Sai Samarth, positioning himself as an empty vessel filled by Sai's grace.
