How does the author of the Sai Satcharitra describe his own role and Sai's influence in the writing of the text in Chapter 30?

In Chapter 30, the author humbly questions his own qualifications for writing the Satcharitra, asking, 'what qualification do I have?' He attributes the entire work to Sai Baba's grace and power, stating, 'He whose work it is, He Himself gets it accomplished. What burden is there on me then?' The author sees himself as merely a vessel, explaining that 'Sai is the illuminator of my speech' and 'the capable lamp of knowledge.' He credits Sai for stilling the wavering of his mind and making the monumental task of writing feel effortless, reinforcing that the text is a direct result of Sai's compassionate grace.
