How does the author describe his role in writing Chapter 38, and what does this reveal about his devotion?

In Chapter 38, the author presents himself with profound humility, likening his role to that of a small child being guided by his mother. He states, "A small child knows how to eat, but does not know what to eat. Whether to feed milk or a morsel of food, that care must be taken by the mother." He then extends this analogy, explaining, "Similarly, my Mother Sai, having placed the pen in my hand, is getting this composition written spontaneously for the sake of His own beloved devotees." This beautiful comparison, found in Chapter 38, reveals his complete surrender and devotion. He does not see himself as the author but merely as an instrument through which Sai Baba is communicating His teachings.
