What is the final perspective of the author of Chapter 53 on his role in writing the summary?

The author of Chapter 53 ultimately concludes that he is not the true writer of the summary but merely a conduit for a higher power. After expressing his feelings of inadequacy, he surrenders to the Guru's will. He states in Chapter 53, 'Sai, the breaker of obstacles (Vakratunda), will be the one to write this summary. His glory is immense; my mouth is merely an instrument.' This shows his complete surrender and belief that the work is being completed through him by Sadguru Sai Baba's grace, not by his own intellectual or poetic skill.
