The author uses metaphors like the 'Titwi bird' and calls himself an 'ignorant person.' What is the significance of this self-characterization in Chapter 2?

In Chapter 2, the author employs several powerful metaphors to convey his humility and the immense scope of his undertaking. By calling himself an "ignorant person" through whom the Lord writes, he stresses that he is a divine instrument, not the true creator, much like the saints Mahipati and Das Ganu who were similarly inspired. The metaphor of the "Titwi bird trying to empty" the vast ocean of Sai's life, also from this chapter, illustrates his profound awareness that completely capturing the infinite nature of Sai's leelas is an impossible task. These metaphors collectively highlight his devotion and reinforce the central idea that the Satcharitra is a divinely guided work channeled through him.
