What does Chapter 30 reveal about the author's self-perception and his role in writing the Sai Satcharitra?

In Chapter 30, the author humbly reflects on his own role in creating the sacred text. He sees himself as unqualified and a mere vessel, asking, 'what qualification do I have? Who takes up this task upon themselves?' He attributes the entire work to Sai Baba's grace, explaining that Sai is the true illuminator of his speech and the 'capable lamp of knowledge' who destroys the darkness of ignorance. The author states in this chapter that he feels no burden or apprehension because he has complete faith that the compassionate Lord is the one getting the work accomplished through him, stilling the wavering of his mind.
